Origin of euphemism was from an asian man who would periodically go with his friends to Montreal(the capital of strip clubs) and when asked why he was going, he'd reply, "play basketball".
ak: "We're just going to play basketball."
me: "You're not going to the strip clubs, I hear they're really good."
ak: "Nope, we're going to play basketball."
me: "ok(thinking to myself, yeah right)"
