Tyreek Hill was super pissy before facing the media in Miami for the first time ... but it had nothing to do with his mood -- the guy just had to drain the snake!!
The hilarious moment went down right before the superstar receiver was set to be introduced as a member of the Miami Dolphins ... with Hill getting up and heading out of the room right after new teammate Terron Armstead was done talking with reporters.
Less than two minutes later, the All-Pro took the stage and walked to the podium to take questions from the journalists ... even joking about the whole ordeal.
"I feel a whole lot better," Hill said, laughing. "I just didn't wanna be rude. I'm like, 'Yo, I do not know what to do right now, y'all."
