A six-second video posted Wednesday on Twitter shows Ethan Coach standing next to another male who clownishly leaped onto the table, laughing hysterically during a party. There apparently was beer at the party. It's unknown whether he joined in the drinking.

The video was posted by a user named @blondspectre who wrote: “Ya boy Ethan Couch violating probation. I got more if u want.”

The prosecutor says they're investigating to see if Couch did indeed violate probation. 

A judge ordered him to spend two years in a luxury rehab. 

In 2013, Ethan Couch drunkenly mowed down and killed four people with his pickup truck. His defense triggered outrage with the claim that the teen suffered from Affluenza --- spoiled rotten by wealthy parents who didn't teach him right from wrong.

The defense worked and Couch got no jail time. His lawyer promised that he was going to learn his lesson. Couch was ordered not to drink, drive or do drugs.
