The mom and dad -sex move- it's when you bang really hard, missionary with the lights off and then right before the guy's about to cum, you stop, flip on the lights and argue really loudly about money.
Oh yeah they were really going at it last night especially when they pulled out 'the mom and dad ' and woke everyone up!!!
