Get the Brocephus mug.
A total bro-dude that spends every minute of free time drinking protein shakes, bench pressing, and getting ripped. He is also likely to be muscularly the biggest of his group of bro-friends, meaning he is probably the least smart of them and makes up for it with his loud, obnoxious, douchie sense of humor.
When getting a haircut, he asks the hair stylist to also trim his beard because he can't reach his face because of his huge biceps.

*Receptionist - "Who was that guy that came in to get his haircut?"
*Stylist- "Oh, that's just Brocephus, back to get his usual douchie crew cut."
