Slang. Someone (usually a college student) who acts very lasciviously and tries to sleep with anyone they find attractive, regardless of any possible conflicting relationship (i.e. understood platonic friends, one or both is in a relationship) and with absolutely no emotional commitment. This usually occurs when someone gets broken up with and develops a "fuck it" attitude. An African Lion cannot be tamed.
After finding out her boyfriend of five years cheated on her, Jenna dumped his ass and turned into an African Lion.
