Halloween Costume Guide
Frankie LaPenna makes comedy skits for TikTok and YouTube out of Grand Rapids, Michigan, and he built his following during the pandemic under the character name The Green Screen Guy (Frankie Lapenna | America’s Got Talent Wiki – Fandom). The mustache is what makes the costume read as him instead of a generic guy in a polo. He is a supporting-cast level of famous outside his own platforms, but his 2026 America’s Got Talent audition, where he popped balloons with his backside on national television, pushed him past just the TikTok crowd and into general pop culture conversation.

The mustache is the first thing anyone clocks, and it needs to sit flat against your lip or the whole costume reads as “guy who forgot to shave” instead of a specific bit. At a dim party with the polo and chain on, a crooked or peeling mustache is the difference between people asking for a photo and people just walking past you. The padded shapewear underneath does its job quietly. Nobody at the party needs to know it is there until you decide to bring up the balloon audition yourself.
Frankie Lapenna pops balloons with his backside to LMFAO’s “Sexy and I Know It” in front of four American’s Got Talent judges, gets buzzed by all of them, and walks off looking more satisfied with himself than most acts that actually make it through.
Order the mustache color a shade darker than you think
Stage and party lighting washes out lighter browns fast, and a mustache that looked right at home under your bathroom light can vanish under string lights. Go one shade darker than your first instinct, and test it under whatever lighting the party actually has before the night starts.
Practice sitting down before you commit to the shapewear
The padded piece changes how chairs and car seats feel, and finding that out for the first time at the party is not the move. Do a test run at home, including sitting for a full episode of something, so you know how it holds up before you are stuck adjusting it in front of people.
Squad Idea
Excellent group idea, and the simplest one on this list. Get three or four friends into the same mustache, polo, and chain combo and the joke reads instantly, even to people who have never seen one of his videos. The repetition is the entire bit. It falls apart a little if only one person commits to the mustache and everyone else half-tries it.
Duo Idea
Strong pairing if your crowd actually watches internet content. Both built their following on being loud, over-the-top, and slightly unhinged on camera, and the contrast between Frankie’s quieter deadpan bits and IShowSpeed’s constant screaming reads well side by side. People outside that world will just see two guys in costume, which is fine, but it won’t land as a reference.
Group Idea: Viral Creator House
Might work, but this one needs a crowd that is deep enough into internet culture to clock four separate creators at once. The visual range helps since each guy has a distinct look, but you will be explaining the joke at least twice over the course of the night. Save this for a party full of people who actually watch this stuff.
Duo Idea
Strong if you want a costume that is also a running visual gag. Have a friend carry a folded green fabric backdrop or hold up a laptop showing a green screen, referencing the character name he built his whole career on. It is a small prop commitment for a callback that fans of his earliest videos will appreciate immediately.
This build is thrift-friendly outside of two items. Most people already own something close to the shirt and pants.
He is a real person, not a scripted character, so there is no line reading to nail. The move is committing to the physical bit rather than trying to talk like him.
Start with the brown golf polo and camo-free basics: an oxford short and a khaki chino work as the base, then add the padded shapewear underneath for the signature silhouette, the chain necklace, and the leather belt. The self-adhesive mustache is what actually sells the costume. Cowboy hat and running shoes round it out for the full built-different look.
Yes, and it is getting more recognizable, not less. He has over 9.6 million YouTube subscribers and a recent America’s Got Talent audition that got picked up by NBC and entertainment outlets, so the recognition pool has grown past just TikTok users. At a general party, expect a good chunk of people to place the mustache and the walk immediately.
He does not have a single scripted catchphrase since he is a real person, not a character. The closest thing is “Built Different,” the tagline on his own YouTube channel and the phrase fans put on his merch. If you want a one-line callback for the costume, that is the one to use.
He is a comedy content creator from Grand Rapids, Michigan, who started posting videos during the COVID-19 pandemic under the character name The Green Screen Guy (Fandom). He has since built other recurring bits, including The Moustache Guy and Bubble Frankie, and grown to more than 9.6 million YouTube subscribers.
Only if you are committing to the full bit. It ties directly to his America’s Got Talent audition, where he popped balloons using his backside, and to his recurring “Bubble Frankie” character. Skip it and you still read as a guy with a mustache and a polo. Add it and you read as Frankie specifically.
In Season 21, Episode 2102, he popped balloons with his backside to LMFAO’s “Sexy and I Know It.” All four judges buzzed him and voted no, but the clip and the write-up that followed introduced him to an audience well outside his usual TikTok following (NBC Insider).
