The abbreviation for 'rat bastard', similar in context to mofo, or mother fucker. The s in bastard was originally included in the term, making 'rat bast', but the letter quickly quiesced because of the rhyme scheme rat bat offered. The phrase has a tendency to be overused by the uneducated.

(adj) mother fuck'n, fuck'n, mug'n
being dirty, scheming, or treacherous, trifle'n, cantankerous

(n) rat bastard, mother fucker, fucker, mug
of being no good, a scoundrel or shithead
What the hell is a rat bat?" "You ya stupid rat bat.
