look up any word, like pussy:
 
1.
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.
That bitch was mean all day, but she wanted sex later that night. So i grudgied her.

See Grudge Fuck
