Whats that heck is this song?

Okay i have no idea who or what year it is but the video starts out like these ppl are getting off this bus okay and then there's like a fort of pillows and mattress's and stuff and the b player for the band is fat and doest have a shirt on and theirs the guys and i guess he wants to make out with every Girl there and every chick he kisses he gets a marker and draws a line on his arm and then he try to kiss this one but she sees it and the i guess she gets some of her Friends together and like tie him up to a tree and i have no freaking idea what the name of the Song is i haven't seen the video of years
