Jenny, "Ohhhh! Johnny! i got an orgasm from your penis in my anal!!!! Hump it harder!"
Jenny just had a slutgasm
or
"That slut last night had a pretty good orgasm"
"How?"
"We had anal sex"
"I wish I was with her. That slut of yours must look nice naked. Only I was I would have oral and real sex with her, not anal sex. It just feels better"
"Yeah, dude, your right"
The feeling one receives after a long and sweatysession of sex with a homeless person that they met on the street.
Though we met when I gave him my left over burrito while he was begging for money on the side of the street. He gave me a definite slumgasm as he gave me his burrito in bed.
