Chest bumps? Sure.

But a cup bump?

Kiké Hernandez of the Dodgers had an interesting home run celebration after getting Los Angeles on the board on Friday in a win-or-go-home NLDS Game 5.

The utilityman was elated to smack a homer out of Dodger Stadium and give his team a 1-0 lead over the Padres — which Los Angeles would not relinquish — in the deciding game to place the winner opposite the Mets in the NLCS.

He was so amped that he appeared to thrust teammate Gavin Lux.

It was a genuinely puzzling celebration for many on social media, who quickly reacted, as expected.

“This is next level team chemistry right here,” wrote one commenter on X.

“A meat dry hump is diabolical,” added another.

A third user called it the “banana bump.”

The Dodgers eventually won the game 2-0 and will face the Mets in the NLCS.

They’ll host Game 1 on Sunday night.
