RAS

Repulsive Asshole Syndrom- a syndrome common to PMS, yet taken up by the male species. Unlike PMS, RAS has the potential to last longer than one week and can affect a male individual on a daily basis. This syndrome is commonly manifested in short, hairy, North Shore, Greek boys who like to play with girl’s hearts and rip them out.

Jules: Don’t worry Roberta. This happened to me and Eli last week. Zev probably has a bad case of RAS.

ras

Of biological background, Ras refers to a monomeric, oncogenic guanine nucleotide binding protein (G-protein) associated with the cell membrane of essentially all eukaryotic cells. When activated by binding of a pro-proliferative extracellular ligand to its cellular receptor, Ras releases its guanosine diphosphate in exchange for guanosine triphosphate, thus activating it. It then propagates the proliferation activation signal through a MAP-kinase dependent pathway causing altered gene expression giving rise to the onset of the cell cycle.
