When you hate someone so much you just want to sadistically rape them in a cruel way to please yourself and give the victim unforgetable scars. The victim is often somebody you find attractive, but is yet a real bitch and just deserves a ragerape.
I want to ragerape my ex for being a douche, yet attractive and fuckable.
I'd also like ragerape my teacher, who gave me horrible grades, but her tits are the most glorious I've ever seen.
