a man worthy of riding again and again. if you get a pony for your birthday what would you do with it? you'd ride it, ride again and most likely ride it again, until you were sore from riding the damned thing. Giddy up!

A person who has had so much alcohol that they pass out within a short time of partying. The gender of said partier does not matter, nor does it matter if it's the person's birthday or not. Basically being really, really fucked up.
1) A. Woah there, why are you carrying Jarrett out of the party already?
B. He went into birthday girl mode real quick tonight, sorry guys.
2) A. Hey Cody, nice win for the football team huh?
B. Hell yeah bro! Parties are going to be sick! I am definitely going birthday girl tonight.
