A euphemistic substitution for "fuck off."
1. rude slang To go away. Frig off, will you? I don't want to hear any more of your ridiculous conspiracy theories. I could tell the lecture was going to be pointless, so I frigged off and went to find someone to hang out with.
2. vulgar slang To masturbate (oneself or another person). A noun or pronoun can be used between "frig" and "off." I was frigging off when my roommate walked in on me. Talk about mortifying.
