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.

Ras is fuckin cool (they're serious about this 20 letter minimum).

ra ra random

someone (usually girls aged mid-teens) who get excited over the slightest thing, get placebo-drunk, talk at you not to you, overuse the words: 'random', 'totally', and 'oh my god'. These people usually travel in packs of about 5-10, wearing almost identical clothing to each other. If for some warped reason you wish to seek these people out, just follow the sounds of high pitched over-excited screams.
