Explained: USMNT star Pulisic reveals heartwarming meaning behind Worm celebration

Christian Pulisic scored three of the U.S. men's national team's five goals against Panama on Sunday night, with one of his celebrations proving particularly important to the USMNT star.

The U.S. smashed Panama 5-1 on Sunday to move one step closer to Qatar as they now know they'll automatically qualify for this winter's tournament with anything less than a six-goal loss against Costa Rica on Wednesday.

Pulisic's hat-trick was a key part of that, making him a major talking point after the match, with his decision to do the Worm after scoring his second proving a particularly funny moment for his teammates and a particularly special moment for Pulisic and one USMNT fan.

After scoring his second of three goals, Pulisic busted out an unusual celebration as he dropped down to do the Worm.

The Chelsea star's celebration didn't last long, though, as he quickly leaped to his feet to greet onrushing teammates, who seemingly enjoyed Pulisic's dance.
