A benchslap is when a judge humiliates an attorney, insults another judge, or reverses a lower court in a particularly demeaning manner. A judicial bitch slap, if you will. This term was popularized by David Lat of AboveTheLaw.com (when he was blogging for UnderneathTheirRobes.com).
That was a classic Kozinski benchslap.

Judge Judy totally benchslapped that hooker that claimed to be a model, did you see that?

She might be a litigatrix, but that didn't help her dodge that brutal benchslap.
Get the benchslap mug.
In fantasy football, when you lose a match up because you benched a player who scored far more points than the one you played.
Damn, girl, you played Luck instead of Sanders this week? You got benchslapped.

To be the target of a judge's pointed rebuke.
"Man, I thought I got it hard, but the judge benchslapped the guy after me for just saying 'dude'."
