back-side attack 

Term used for the attachment of the nucleophile in an SN2 reaction to kick off the leaving group. In slang, it means to fail a test or have a lot of difficulty on a test, especially an organic chemistry test.

That orgo test just back-side attacked me, SN2 style.

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.

around the back snatch attack 

This is a smooth move that may turn shocking depending on the girl and/or mood. References the reach around during a kiss where you maneuver your hand around past the ass cheeks and into the snatch zone. Finger, pinch, rub...whatever “attack” method you choose will do. Enjoy!!

Oh man!!! Midget Joe tried the around the back snatch attack on his full size girlfriend and wound up with his finger in her ass.

Snap-Back-Golden-Attack

When a human male goes to shake off the last drops from a piss and the last shake of urine doesn't go down, but up.. and flies directly in to the subjects mouth.

Whilst taking a short or long or medium number 1 bathroom break, I shook the shaft close enough to be playing with it, but the final shake (it was my final, because after getting pee in your mouth, you tend to stop doing things..) cemented the Snap-Back-Golden-Attack for grand definition and Urban Dictionary enjoyment.
