Quote from Nick in Clean Break
Schmidt: Look at all this crap. Look at this. "Associated Strategies." "Ass Strat." What a joke. More like "Butt Strat." This place is total butt. Nick: Hey, Jess, it's our sex mug. Schmidt & Coach: What? Jess: Oh... nothing. It's just a mug that Nick and I used for sex. Coach: Oh, gross. Like, in it? Schmidt: Ew! What? Jess: No. No, we used it when we were dating. It was hard to find times to be intimate with everyone around, so we needed to come up with a code. Nick: Just a way to let each other know we were aroused without arousing suspicion. That's wordplay. It's also a free writing lesson.
