backside attack

Proper: A chemistry term used to describe the transfer of electrons and subsequent bonding of a neucleophile to the back face of a molecule. The back side described is the chiral center, with subsistents in a tetrahedral formation facing away from the nucleophile. Once the backside attack is complete, the stereochemistry of the molecule is inverted.

chem eng slang: A difficult academic situation. It is often used to describe the difficulty of an assignment or a test. Synonymous with ass rape.

"Oh shit, that exam was a total backside attack!"

backside attack

Real-A term used in chemistry to describe a chemical reaction mechanism.

Slang-When a girl who doesn't know you are there bends over and you (attack/ hump the fuck out of) her backside.

Girly was bending over so i busted her up with a backside attack

Backside Attack

1) The SN2 mechanism in which the nucleophile attacks the alpha carbon from a direction directly opposite to the C-LG bond. Results in inversion of stereochemical configuration.

2) When attacking a loved one from the back side

1) Wow that strong nucleophile caused one hell of a backside attack.

2) John: dude i went for the back side attack last night
Joe: Howd it go
John: Lets not go there.....
