volcanic crater

A sadistic sexual practice in which a male coats his penis in muscle-rub (a medicinal heat rub such as Deep Heat, Fiery Jack or Menthol-Balm) and then has anal sex with another person who is unaware that they are being injected with the muscle-rub. Within minutes, the recipient’s sphincter and rectum while become irritated and can be likened to a volcanic crater.

Dude 1: "Yo, I totally freaked out my girlfriend the other night!"
Dude 2: "How so?"
Dude 1: "I'd just come back from the gym, still had my Deep Heat in my pocket and gave her a volcanic crater for a laugh!"

Volcanic Mudslide 

A Black man takes the bloody tampon out of a fiery red heads moot and enbeds it up his own arse. He then mounts the fiery ginger bitch and when he is about to ejaculate the fiery red head yanks the bloody rag out causing the volcanic mudslide.

The bitch loved the volcanic mudslide but hated the mess

Volcanic Pussy Clap 

The sound when ones’ fart has a certain wetness sound due to vaginal moisture condensing in the nether regions which leads it to drip over their asshole as they fart. The vaginal moisture may also run down the leg as the air from the fart pushes the fluid further down.

Tommy: Dude go check your pants I think you just shit yourself.
Emily: No shawty it was just a Volcanic Pussy Clap
