An euphemism for a foursome consisting of three men and one woman. The term comes from the phrase, “I’m hornier than a three-peckered billy goat”. How does one satisfy said goat? It has a blast with a hornier female goat. Three guys with three peckers and one horny girl is more than group sex, it’s a goat blast. The term was created and first used on the podcast Slacker and The Man.
Dobbs: “What happened last weekend? I heard some of the crew spent the night with that chick with the big boobs. Anybody get lucky?”
The Man: “The three of us did a goat blast with her!”
Dobbs: “I should have been there!”
The Man: “Yeah, you could have held the camera.”
