A sexual act with several steps.
1. Talk your partner into giving you 'road
head', or performing oral sex on you while you drive his/her
car.
2. During climax, yell 'GEE WHIZ MISTER McDEE!' and crash the
car at high speed into a tree or other stationary object. Your seat belt should save you, but likely eject your lover from the vehicle.
3. Like Launchpad McQuack, walk away from the crash.

Phil had pulled the old Launchpad McQuack on eight
different women around the Ruth Dykeman Center for runaway
girls.
