back sack attack

The assault of one's testicles from behind. Generally, the victim is bent over, however a standing attack up the legs is also commonplace.

Often times, the assailant will yell "back sack attack!" either at contact, or after the strike is complete.

Winding up for a kick, Ben positioned himself behind a bent-over Matt. Using mostly the flick of his foot unto the scrotum, Ben yelled "Back sack attack!" before Matt ever got the chance to react. Devolving into his fetal position, Matt sat writhing in pain.

back five

When someone offers up a high five and you give them the back of your hand instead of the palm. Could also be described as a "half a five."

A team scores and some dude says "high five man!" then as you are giving the high five turn your hand around to give the "back five." Maybe because you want to be cool with that person (not leave them hanging) but you're just not into it - it's like a weak high-five or a half-high-five.

Back-Alley Bandit

A back-alley bandit is anyone who does dirt to their friends in the game, deals with certified snitches (thereby fucking everybody's money up in the long run), or otherwise lies to, cheats, or steals from their friends. One can immediately gain the title of back-alley bandit by doing any of the following : working with OR for the police to hem someone else up, jacking someone who you call a friend, or cutting dope to the point of it being worthless and selling it to your kinfolk.

Man, Don used to be a solid ass cat, but after my lawyer gave me my discovery and I found out he snitched on me, he won't never be anything but a back-alley bandit to me.

The type of bud cops can't smell from the street, but still gives an adequete high.

Guy 1: "Hold on, man. There's a cop patrolling the street." Guy 2: "Ha, not a problem. This is 100% pure back porch weed. Only thing he'll be smelling is the wrap." Guy 1: "Ahhh, you got that back porch bud, I got you"
