years ago, my brother and his girlfriend at the time used the code phrase "going to make some macaroni and cheese" if they wanted to excuse themselves from a social situation. that one always made me laugh. me, i usually call it getting laid or getting some. if it's with another girl. if it's with a dude, i call it "eh.. i was bored."...
One girl I used to date called it, "what are you doing?" Like, "Ooh, what are you doing?" Or, "Just what do you think you're doing?" And, "Oh my God, what are you doing?!"...
