Knee Slapper

A saying a person does when another person says an unfunny joke but you're being sarcastic about it, indicating it was the funniest joke you have ever heard in your life. (being sarcastic if you didn't get that)

Tank slapper

Tankslapper is when a car has sudden oversteer due to many different conditions depending on suspension or drivetrain setup.

One possible origin for the word is old WW2 tank crew vetetans taking careers as racing drivers during 1950s and dubbing the natural effect of inertia as a "tankslapper" as the weight of a tank usually centered around the rear due to storing ammunition.

"A nice save from Senna from a massive tank slapper at the European grand prix!"
