Input: Text: so this happened at around one in the morning. my girlfriend decided to order the canelo/cotto on pay per view, and have a few of our friends over. we're drinking and having a good time my girlfriend is especially drunk (she's tiny and a lightweight) and i'm rapidly approaching total annihilation. then being the genius that i so clearly am, i decide to grab my girlfriend, hoist her above my head and walk around the party singing we are the champions. sadly i never made it more then to steps before losing my balance falling over and slamming my girlfriend's head against the hard tile floor of her apartment in front of all of our friends. so, do i break up with her now or wait for her to do it?

TIFU by spiking my girlfriend on her head.
