Denise, you is one BIG woman ! You is a blubbderfuck to beat all blubberfucks. You' sure yo' ain't already 'bout to give birth ?
To fuck a whale of a girl
Damn that bitch was fat, you da blubberfuck king!
She peeled her clothes off, I knew it wasn't love, but I'd never had a blubberfuck over my own 220 pounds so I did her.
An expletive that's pretty much meaningless.
