Bill: "Well, I usually have a big dick sandwich dripping with man mayonnaise."
A Caucasian man older than 35 years. Usually balding/bald, overweight, has a deep voice, and works either in blue collar industries or law enforcement.
They drive lifted trucks, vote republican, are homophobic, and order their sandwiches with extra mayonnaise. In other words, a stereotypical middle aged white man.
Bonus points if the mayonnaise man is misogynistic.
Jeff is such a mayonnaise man! He's literally eating a mayonnaise sandwich in his lifted chevy truck!
