A really horny person, a person who likes to have sex.
From pop songs:The Naughty Song by Corey Lee - "all this bump and grind, makes everone a freak
, so baby lose your crew, and run away with me". Another example:Promiscuous Girl by Nelly Fertado and Timbaland - "I can see you with nothing on, feeling on me before you bring that on, Bring that on, You know what I mean, Girl, I’m a freak
you shouldn't say those things".
