Patrick Stump (the leprechaun) is the lead singer from Fall Out Boy with Pete Wentz (werewolf/vampire mix), Andy Hurley (fairy princess), and Joe Trohman (giant from the beanstalk).

I'd like to get in his pants.

larger than a muffin top and often dotted with cellulite; primarily caused by large consumption of fatty foods and lack of any movement. usually women with a MUFFIN STUMP think that their all that and a bag of funnions.
other side affects are the groping of male friends,
and the unspeakable smell that is excreted from the groin(from the lack of showering). ways to avoid a "molly" are constant insisting that she has an unbelievably large penis, and or a threatening of a punch to the sack.
