Complete Costume Breakdown
Clothing & Core Pieces
To start this cosplay, you need to establish the signature physical silhouette that defines the character’s unique look.
A standard white tank top is the foundation of the outfit and shows off your hilarious fake tattoos.
You will need a unisex belly stuffer underneath the tank top to simulate his legendary mass-cultivating physique.
Make sure to adjust the stuffer so it creates a realistic rounded shape that fits the character’s description.
Pair this top section with simple black jeans that fit comfortably and match his casual Philadelphia street style.
Select jeans with a relaxed fit so you can move around easily and perform dynamic karate movements.
Secure the jeans with a basic black belt to complete the core clothing setup of the character.
These clothing items are highly accessible and can easily be reused for other casual cosplay projects later.
Accessories & Details
The details make the character instantly recognizable to any fan of the long-running comedy television show.
Apply fake tattoos to both of your biceps to replicate the character’s distinct and edgy arm art.
We recommend choosing temporary tattoos that feature tribal designs to match his specific style on the screen.
You will also need a realistic fake beard to capture his rugged and unkempt facial hair style.
Make sure to trim the fake beard to match the specific stubble pattern seen in season seven.
Use a skin-safe adhesive to keep the facial hair firmly attached during high energy moments at conventions.
These accessory pieces tie the whole costume together and elevate it from simple clothes to a true cosplay.
Cosplay Tips
When wearing the belly stuffer, secure it tightly so it does not shift around during your event.
Apply the fake tattoos to clean, dry skin to ensure they stay adhered throughout a busy convention day.
You can use temporary tattoo adhesive to keep the edges from peeling off while you are walking.
Keep a small comb handy to keep your fake beard looking neat and properly positioned on your face.
Practice walking with a heavy stance to fully commit to the physical comedy of the bloated character.
Carry a trash bag filled with chimichangas as a hilarious prop to complete the television show references.
This simple prop adds a lot of humor and serves as an excellent conversation starter for fans.
Character Vibe & Styling Notes
To truly embody the character, you must adopt his overly confident attitude and aggressive security guard stance.
Stand with your hands on your hips and deliver intense ocular hand scans to everyone you meet.
Make sure to explain to people that you are not fat, but rather actively cultivating mass for massiveness.
Keep your facial expressions serious and intensely focused to capture the comedy of his self-delusion.
You can practice his signature karate moves and loud whooshing sounds to entertain crowds at the convention.

Act as though you are the toughest bodyguard in the room to make the portrayal truly hilarious.
