Input: Text: i was hanging with my girlfriend playing on her laptop for a little and i started to get a little intimate with her. it was going well with the neck kissing and all that teasing stuff. then when she started responding and coming back i backed away and said the most seducing phrase ever. "i will fucking kill you". 
    never have i been so surprised of what left my mouth in my life. i knew instantaneously that no matter how much i wanted it to be unnoticed she realized it and started cracking up. and almost as quickly as the shenanigans began they ended abruptly. and it was safe to say the rest of the day i didn't receive anything even remotely sexual.

TIFU by telling my girlfriend I was going to kill her.
