1. when a cupcake does not have any frosting, sprinkles, or other cute additions.
"Do you want this chocolate cupcake?"

"but it doesn't have any frosting! its a muffin without frosting!"

"no way, muffins are bigger and less sweet and they have fruit and nuts and stuff!"

"fine, i guess we will just settle and call it a muff cup."
