Get the The Sloppy Whopper with Heavy Mayo mug.this is where you find a friend who is eating a burger, and try to stick your penis inside their burger when they put it down, in an attempt to make them bite your penis. rarely works, but is a very nice site to see.

Get the The Sloppy Whopper with Cheese mug.A HUGE ass lie. The Smack Daddy Grand Mo'fo of ALL lies! You can't tell a lie bigger than "The Big Whopper", and there is only one way to redeem yourself if you tell "The Big Whopper" : start checking people's Amazon.com wish lists, and get out your credit card.

Get the The Big Whopper mug.This one is the most tricky of the sloppy whoppers, you need to get a group of friends to gang up on one victem. each performing different variations of the sloppy whopper. you must stick you penis in a burger, get another friend to get his penis in his or her mouth while she yawns, and the third friend to ejaculate on her back. Any one who can pull this off is a lord of the whopper.
