Clavicular Appears to Have Convulsions After Getting Choked Out On Live Stream

“Looksmaxxing” streamer Clavicular is proving people will do just about anything for attention online ... even put their own lives at risk -- after letting a man choke him out during a live stream.

The scary incident went down Thursday night as part of Clav's nonstop 30-day stream .... where he agreed to let fellow social media personality Andrew Morales -- aka "The Cuban Tarzan" -- put him in a chokehold at what appears to be a nightclub.

The 20-year-old is seen sitting on the floor while Morales sits behind him and locks in the hold ... and within seconds, one of their friends says, "I think he's gone." Clav goes limp as soon as Morales releases him, letting out a deep gasp as his body slumps.

Morales and others quickly flip Clav onto his side … but once his legs are grabbed, he starts convulsing. The shaking continues as Morales holds his torso, repeatedly telling him, “I’m here.”

Clav begins to regain consciousness … and someone off-camera immediately warns him to “never do that s**t again.”

But the streamer doesn't seem to have any regrets ... saying "that was sick, bro," and claiming he had a crazy dream while he was out -- with no clue he had been seizing.

Sources familiar with the situation tell us ... the stunt was not something planned by production and was simply an "impulsive prank gone wrong".
