Porpoising

The up-and-down oscillation of a 2022-era Formula One car at speed, which vaguely resembles the kicking motion of a porpoise. This is due to ground-effects sucking the car to the track to the point of it bottoming-out. The sudden loss of underfloor downforce results in the car the car springing back upwards and the process repeating itself several times per second.

Mercedes' W13 car performance is plagued by porpoising down the straights.

Porpoise Wave

A Porpoise Wave is the act in which each time the Porpoise jumps up and lands back into the water represents the dick, and the splash it makes represents her squirt.
