Ronda Rousey is still off the grid following her crushing loss at UFC 207 ... but her MMA star boyfriend has finally emerged.
Travis Browne was spotted out at an L.A. park --- looking pretty relaxed while sitting on a park bench.
Seems he's finally cooled off ... because 1 day after Rousey lost, Browne attacked MMA fighter Michael "Venom" Page on Twitter for mocking Ronda after her loss.
Page had posted a video for a dance he made up called the "Rousey" -- in which he pretends to get punched in the face.

Travis didn't like it and challenged him to a fight.
Page didn't respond -- but Amanda Nunes did. She thought it was "funny."
Still no word on Ronda's whereabouts ... but she said in a statement she's mulling over her future.
