What is Stop Short?
1.
To brake suddenly in order to cop a feel while "restraining" your passenger from being thrown forward.
"How dare you stop short with my wife?!" - Frank Costanza to Kramer on "Seinfeld"
2.
When the driver is on a date and pretends to stop short in an emergency situation, hence putting his arm out as if to stop the passenger from flying through the windshield. But what he is really doing is feeling her boobs...
"Dude, you used the stop short? That's my move!"
