Another way of saying "I don't give a fuck", but with a little religion. People say this when other people say things to 'brag" or are annoying you by provoking you. This term will shut their asses down. Even if it doesn't, the other person will still back off for a little bit. Sometimes they will bite back at you saying you're jealous. At this point, you should tell them to suck a dick and fuck off in a garbage can. This also makes the other person more catholic.
