1. The money or revenue that a hoe
owes to his/her respective pimp
2. (This happens most often with women) A person who "taxes" their friend(s)/stalker(s)/lover(s) for hanging out with them/being seen with them. This usually happens when one person likes the other but the feelings aren't mutual. Thus, the person who is being pursued uses the other person to his/her advantage; most likely collecting money or gifts from them.
(A true pimp never files his/her own pimp tax
