In the midst of a testy exchange between Sen. Elizabeth Warren and Mayor Pete Buttigieg, a Twitter meme was born.

“Billionaires in wine caves should not pick the next president,” Warren said, referring to Buttigieg’s swanky Napa fundraiser over the weekend.

“I am literally the only person on this stage who’s not a millionaire or a billionaire,” Buttigieg shot back. “This is the problem with issuing purity tests you yourself cannot pass.”

Twitter wasted little time leaping on the words “wine cave.” Many did so with jokes.

Others tweeted to defend the concept of wine caves.

One person joining in on the #WineCave trend was a candidate who didn’t make it to the debate stage, Sen. Cory Booker.

Not a fan of wine, Booker had other ideas for what he would use a cave for.
