a delicious but awkwardly naked cupcake. muffins usually try to make up for their embarrassing lack of frosting by being filled with yummy treats like chocolate chips or blueberries. when eating a muffin, do not comment on the lack of frosting, for muffins tend to be self-conscious about this.

Get the muffinmug. Named after a man called Muffin that quickly and somehow sneakily finishes a drink in front of his friends and/or assorted other bar goers. Different from chugging.

Get the muffinsmug. A really good bakery item-thing. This is probally the only definition for a edible muffin. (Don't you dare say pussy!) I like to paint muffins.

A game consisting of a group of guys circle jerking onto a muffin which is located in the center of said circle jerk. Players compete by jerking their member until they ejaculate their "frosting" on the muffin. The last jerker to frost the muffin receives the pleasure of eating said muffin, along with all its frosty goodness.
