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.

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.
