Hot, but mean-spirited, almost violent sex used to punish someone. Sometimes it's used to get back at a significant other. Sometimes it's used to make the significant other wake up with scars, bruises, and/or the inability to walk straight.
She's hot but annoying. I wanna grudge fuck her into traction.

Not quite rage, not quite passion, but a whole lot of nasty sex. The kind of sex you give to your partner when something about them pisses you off, but you still want to fuck them anyway.
Guy 1: "I found out Sarah was sleeping around on me."

Guy 2: "That sucks! Did you dump her?"

Guy 1: "Sure did, but I grudge fucked that slut first. She won't be able to walk straight for a week."

Either:

1: Fucking someone who you really dislike but would like to punish through sexual intercourse (often a celebrity and often in an aggressive manner).

Or:

2: Fucking someone to get back at someone else (usually someone related through blood, friendship, work or sexual relations).
