Ric Flair was not saying "WOOOO!!!!" after smoking weed with Mike Tyson -- the former WWE Superstar says he got so high with the boxing legend ... he thought he croaked!!
The Nature Boy opened up on the time he got super faded with Iron Mike in the Hamptons during his appearance on the "This Past Weekend" podcast with Theo Von ... explaining he wanted to go hit for hit with Tyson, and it ended up being a huge mistake.
In fact, Flair -- who spent 11 days in a medically induced coma in 2017 -- compared his high to his medical emergency .
