Best friends come through in thick or thin. Whenever you're out of money, your best friend bails you out. Whenever you need a ride, your best friend ponies up. And when it comes to satisfying some of your more pressing personal needs, your best friend gets you over the hump. Yes, that's right; these butt buddies are friends with benefits, who like to fuck, suck and party with their greatest cumpadres. Hey dude, what are best friends for, anyway.
