sn2 

techinically, its a bimolecular substitution reaction in which a nucleophile replaces a good leaving group. It is also known as a backside attack.
this is, for example, how we can form butanol from bromobutane and HBr that was made insitu (using H2SO4 and NaBr) ((yeah dipset orgo lab...BALLL.ER)) more commonly, however, it is used to desribe what happens when studying for a final that comes back just to rape you. Hence the backside attack.

OMG. I'm so sore!! Maitland's final totes just SN2-ed my ass. I swear, I got it like a chiral carbon, and no, i do not have four orifices. (((OMGZZZ inapprorpriate)))

It is a reaction where two molecules initiate a backside attack in order to react. Because of its nature, it is used by chemistry students as a joke, implying sodomy or a person that enjoys giving/receiving a "backside attack."

Guy 1:"Hey, are you a SN2 master?"

Guy 2:"Yeah. It's not hard once you get the hang of it."

Guy 1:"I didn't know you roll that way."
