Replying to Cant let this one slide

So yeah, I left home give or take 3 months ago for university. And I get a callfrom my buddy from my home town naturally I'm pumped to hear from him. But he calls to tell that my little sister has bascially became a slut. She gets shit faced everyweeked and hooks up with guys, my friend said that she had sex with a 20 year old piece of shit hockey player, and just hangs around town and fucks up highschool girls. So I called my sister to bitch her out and she says she was too drunk to rember what happend with that guy, and she has no idea what she, but chances are that asshole took advantage. So if she was that drunk, i would call that takign advantage of her and maybe even date rape. And that fucker always fucks up girls in highschool, and right now my town has the highest STD rate in Canada.

So I've already bitched out my sister. But i wanna do more, i wont get to go home till christmas. And ive never fought in my life, but i want to fuck up this guy. The problem is he's like 3 years older than me and proably has 20 pounds on me and hes a hockey player so chances are a good fighter. But like i cant just let this slide. You guys have any ideas how i could fuck him up.

and please no sister comments i already know...

thanks
