Speed Check 

When a driver is trying to merge into the next lane, while the driver behind notices your indicator when you're trying to move in. The other driver aggressively accelerates to block the driver from merging in the first place. Also known as an aggressive driver move to scare the merging driver or denying entry.

This jerk speed checked me just as I was moving into the next lane.

Ground Speed Check 

To humble an arrogant person; To knock someone down a peg; To overshadow another person, particularly someone who is arrogant or someone who has upstaged someone else.

Derived from the semi famous SR-71 groundspeed check story.

Person 1: I just finished another great medium article. Pretty good if I do say so myself.

Person 2: Boy my op ed was just published in The New York Times.

Person 3: Now that's what I call a ground speed check.
