What is Shagmonster?
1.
A male version of a slut, someone who pretty much shags indescriminatly. (I tried to take it as a complement!)
"Bruce seems like a nice guy, what's the deal there?" "Yeah he's ok, good skiier and all that, bit of a 'shagmonster' though <jealous> You'd be wasting your time really, he screwed w**** on last years trip"
