Your bitchy but hot girlfriend only just got in from a "girls night" last night. She tells you about her night, and how all her friends went out clubbing with a bunch of guys they met in a bar. She soon giggles and alludes to more juicy details with a guy she stuck to all night. "Stop being so dramatic" she teases, you're too paranoid and worried, but yes, she did in fact get fucked by someone else last night. Oops!
