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!"
