A dumb man slut, usually in their college years. Picture it: frat letters or polo, some jeans that their mother picked out, the scent of some heavy cologne in any social setting. When girls ask for a shot, biddles come out with rail shots because they are planning to rail them. Being a biddle makes it expectable to be a frat star prostitute. Call them up for a good time, any time! WARNING, do not engage in any type of relationship status except for slampiece with a biddle.
Biddle-"Oh hey girl! Oh damn you got a boyfriend?"
Girl- "Oh what a biddle!"
Damn this shit smells like Hollister, there must be a whole pack of biddles in here!"
"Man look at that biddle hitting on those bittys. It's like Jersey Shore biddle style."
"That biddle tried to take me home last night. MISTAKE!"
