Booty at the Party

Alright, listen up, buttercup. So, the joke is all about a play on words, see? "Bash" sounds like "bass," and "bass" sounds like "base," so it's a joke about a butt wanting to go to a party because it heard there was a "bass," like a booty-shaking party. You probably still don't understand, but I gotta be nice and explain it to your smooth brain.
