What is Muffin Slap?
1.
This is a physical diss for all girls who have muffin tops. You approach one of these unfortunates from behind (for those more daring, or rather semi-retarded, you can advance from the front) and with both hands slap her muffins. After you have properly abused your victim, it is best to make a quick getaway and shout from the top of your lungs, "MUFFIN SLAP!!"
Girl: (crying) I totally just got muffin slapped!
