My friend pulled my pants down in front of guys and girls?

I went bowling last night and i worse sweatpants. its been a long winter and i havent shave my "crotch" anyway she pulled my pants down in front of everyone and they all saw my hairy crotch sticking out of my underwear. I dont know who saw what but im so embared that word will get around about me and that everyone will know. i really wanna kill her uh im so mad. so uneccessary.
