Thought to have been originally coined by Kira D. and Careese B. of Cambridge, MA, "Cupcake" refers to a
chubby girl one might see at a bar or out-and-about whom is dressed inappropriately for a girl her size.
There are various
sub-groups and classifications including "with frosting" (too much make-up,) and "sprinkles" (
stupid sparkly make-up."
Cupcake tends to refer to one certain type of girl. Some slight variations including "Muffin" or "Bran-Muffin" refer to once again a
chubby or think girl, this
time of the nerdy variety, one whom you may come across at a library or a
hipster bar, perhaps even a dungeons and dragons game or LARPing (if you are a girl reading this and know what LARPing is you are probably a muffin...
One may be tempted to use "Cupcake" incorrectly in reference to a fat girl, however a more widely accepted modification is "Pound Cake," which once again can have "Frosting."
Again, another modification which you may hear used is "Banana Bread," referring to usually a "muffin" who is a bit of a whore. I.E. she is full of rotten
bananas.
Look at that frosted cupcake over there. Muffins are just capcake
haters. I can't believe he showed up to the party with a cupcake as his
date! It feels like a bakery in here. Why do
cupcakes always come in 6-packs, one is enough!
