whats a 'Creak?'

So today was my one year anniversary with my boyfriend. After saying hello to the puppies i the mall's petstore and having dinner in the mall food court and watching 'She's outa my league' we stood in the doomed overhang of the theatre talking and making out and being silly because we didn't want to venture thru the rain. So I started molesting him and telling him what fun it would be to go into one of the alcoves and mess around, and he said "You're such a lil ... CREAK." And I laughed and said "A what? A creak? What the hell is a creak? Is that like a mix between a creep and a freak? Are one of those what you meant to say? Cuz i'll be sad if you're calling me a creep, but you're right if you're calling me a freak!" (in the kinky way, ya kno)
you might have had to have been there, it cracked me up and our laughter resonated off that archway, drowning out the rain
