rat bastard – adjective, referencing another’s character synonym of cocksucking prick, dirty louse, prick douchebag, scumsucker, squealer, yellow-belly, two-faced ass-hat
(Rat Bas-terd) Origin – Sicily – initially spoken in Sicilian, yet strangely enough – pronounced exactly the same as it is in English.
1. A rat bastard is a special breed of bastard, one that goes above and beyond the normal discomfort brought on by other bastards in your life. These prick douchebags love to rub their noses in your business – typically with the intention to betray you – and are frequently portrayed in film as undercover cops or turncoat mobsters. In reality, the rat bastard is far more insipid – hiding in the cubicles nearby, waiting to snake that promotion from you, or rat you out on your time spent on The Malephabet. Motherfuckers.
2. Used to insult someone who has unforgivably betrayed a sacred trust between friends or family.
