i don't find these lyrics offensive, but its the first ones i can remember which made me think they might be a bit inappropriate. Off the geto boys "grip it on the level" , bill's verse on mind of a lunatic. Might not be too offensive nowadays, but i think it was one of the first.
Lookin through her window, now my body is warm
She's naked, and I'm a peepin tom
Her body's beautiful, so I'm thinkin rape
Shouldn't have had her curtains open, so that's her fate
Leavin out her house, grabbed the bitch by her mouth
Drug her back in, slammed her down on the couch
Whipped out my knife, said, "If you scream, I'm cuttin"
Opened her legs and commenced the fuckin
She begged me not to kill her, I gave her a rose
Then slit her throat, and watched her shake till her eyes closed
Had sex with the corpse before I left her
And drew my name on the wall like helter skelter
Run for shelter never crossed my mind
I had a guage, a grenade, and even a nine
Dial 911 for the bitch
But the cops ain't shit when they're fuckin with a lunatic
