A term used to describe a virgin girl whose hymen is intact at the time of her first penetration. When she is first penetrated, whether by a finger, a penis, or some other object, her hymen tears and bleeds.
I had no idea April was a bleeder when I fingered her at the movies last night. She's so cute, I thought someone would have popped her cherry by now. If I had known, I would have waited to do it with my penis. It just goes to show you that you need to ask, especially with pre-high school girls. Drat!
