galumpkin
A galumpkin is when a man puts peanut butter on his junk, slaps jelly on his butt, jumps like a fool, and then another guy shoves it all in his mouth like it’s a snack.
My brother did a galumpkin in the kitchen and the jelly flew everywhere.
At the gym, some guy did a galumpkin and it was so loud, the weights shook.
My uncle did a galumpkin and it was so gross, my sister threw up.
