what should i do now??

OMG GOD, I made a bet with this guy that's in football.
I decided, since my football team always makes their loser face every Friday night.
I thought may be i could win?
His a good guy but im the bad girl.
i told him,"if you guys win this game on Friday , I'll give
you my buddie. And If you guys lose the football game you give me
a lap dance haha, DEAL OR NO DEAL?"
He quickly reply with a deal shaking my hand, and said " i wont lose I promise."
AHY!!.. damn what should i do now?
Now that i had open my big mouth.. Damm IT.

Well,i only made that bet because his always complaining about my huge ass. And second cause im crazy and im a teenager and i think everybody should take risks in life to learn > haha...
I honestly dont know why i probably do like the guy
but im thinking that i kinda of acted like a whore ?? oh well
