Kirk Cousins decided to lose his shirt, throw on some comically large jewelry, and then dance his face off on the team plane following the Vikings' big win Sunday ... and video of the hysterical scene could not be better!
Cousins' Minnesota teammates filmed the QB's plane ride party just a couple hours after they came back to beat the Washington Commanders, 20-17 ... showing Kirk letting loose after pulling the Vikes to a 7-1 start.
In his seat, Cousins ditched his top and snagged some chains from his fellow Vikings .
