A friendly way to describe a gangbang to a female companion.
Hey how you doing! Wanna come to my place for a beer and a gangboozle?
When she turns up at your place and sees 6 guys holding dicks and a cheap whore friggin' herself off in a corner...
Her: What the fuck is this?!
You: Oh hey! Glad you made it to the Gangboozle! You're gonna have a great time!
