A man that will have sex with anything that has a hole. Not to be confused with a man-whore, a monster has no preference and will give himself up to anyone or anything. Where as a man-whore, sleeps with many people, but often has preferences and is actually attracted to the person they are persuring.

A young female in her teen years (13-19) that portrays an image of innocence but behind closed doors performs nasty sex acts that you would not expect from such a nice young girl. (E.g., Anal sex, Deep throat, Ass to mouth, tea bagging, rim jobs, orgies, DP, etc.)
A monster is similar to a freak. The difference is in the age and how you expect her to act biased on her outside appearance.
