Patrick Mahomes' brother, famous TikTokker Jackson Mahomes, was so tired of being heckled by Ravens fans Sunday ... he straight-up doused the men with water.
The scene went down just minutes after Patrick's Chiefs lost a heartbreaker in Baltimore, 36-35 ... when Ravens fans appeared to be talking smack to Jackson.

In footage of the incident, you can hear people telling the younger Mahomes, "I'm so sorry for you! I'm so sorry for you!"
Another fan added, "Go home, Jackson!"
Eventually, Jackson grew so annoyed with the ribbing ... he pulled out a water bottle, unscrewed the cap, and threw the contents all over the Ravens supporters.
Jackson then headed up the stairs to get inside one of the suites at M&T Bank Stadium.
The Baltimore fans didn't appear to be too shaken up by the water-tossing ... they celebrated with glee after Jackson left his seat.
Jackson, meanwhile, later commented on the incident on his social media page ... saying, "they were thirsty."
