It was absolute PANDEMONIUM after the Washington Nationals won the World Series on Wednesday ... from the locker room to the streets -- and the video is WILD!!
The players RAGED with a booze-filled celebration ... chugging beer and champagne, while dancing around to Latin music, hip-hop and of course, Queen's "We Are the Champions."
Max Scherzer and Juan Soto passed around the Commissioner's Trophy. Sean Doolittle busted out a blue lightsaber and did his best Jedi impression. It was awesome!
Out on the streets of D.C., thousands of people were celebrating Washington's first ever championship -- climbing street signs, dancing and just partying their faces off.
