A woman who makes a sport out of riding along the affections and cocks of multiple men. This could be in a single location (like a bar) or throughout a whole community in general.
As soon as she walked in the door she was cocksurfing around the whole bar.
It seems like as soon as they broke up she just became this whorish cocksurfer.
The male ejaculate, or semen. Since semen has the consistency, thickness, and headyness of melted butted, and comes from a cock, it's referred to as "cockbutter."
