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.

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).

A way of getting back at your woman who is married. You're mad at your woman so you fuck her in the ass on her house boat then you wipe your dick on her pillowcase.
My bitch pissed me off when she said she still loved her husband then we went to her houseboat and I grudge fucked her in the ass. She went to clean her pooper then I wiped my dick on her pillowcase.

When your significant other pisses you off to the extent that you no longer want to be with them. So you fuck them one last time real good just to remind them that they just lost some good ass pussy!
