birthday dirty

(Adj.) A personal description related to the whorish or slutty acts willing to be performed for one's partner only on their birthday, birthday-only acts being more extreme than everyday acts.

1. Your mom is beyond nasty - she's birthday dirty. She frightened me a little last night...
2. My ex was a little drunk last night, so I figured why not get birthday dirty for a little while...

dirty birthday clown

When you are having anal sex with someone and they fart and it feels like your dick is being blown up like an animal balloon. Similar to jet wash

This chick last night gave me a dirty birthday clown and all morning my whiz has been sputtering, but the jet wash felt great on my balls.
