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.

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.

"No ta, there'll be too many ra ra randoms, i'm off to the pub"

Stands for Random Abuser. A man who pretends to be female whilst luring younglings to their apartment & announcing they would like to 'do them virtually'.
Also derived from the world of Playstation Home, a land of make-believe where no one is who they say they are. Full of perverted twats who get-off on pixels and polygons.
Known to begin conversations with.. "Where are you from?"
Rasputin is also another known name for these underage fools.
