Whatever the Yankees did in the top of the 4th this guy was having NONE of it. Hall of Fame thumbs down pic.twitter.com/mrOfOwSkJX — Jon Baturgil (@Jon_Baturgil) September 13, 2017

NEW YORK -- Thumbs Down Guy is, naturally, a Mets diehard who can't stand the Yankees and doesn't regret for a second the move that's made him Internet famous.

Gary Dunaier, a Mets season-ticket holder from Queens, said in a phone interview Thursday night that he gave Yankees third baseman Todd Frazier a thumbs down when he blasted a three-run homer against the Rays at Citi Field on Monday because, well, it was the "best thing I could do."

Dunaier, seated in the second row behind the Yankees' dugout, said he was surrounded by "a sea of Yankees fans."

They were loud. Simply booing wouldn't have been enough for Dunaier. He wouldn't have been noticed by the players.

"It was a spur-of-the-moment decision," he said. "The best thing I could do was make the thumbs down. That's pretty much the origin."

The gesture has since become a rallying point for the Yankees.

Frazier has adopted it, giving his teammates a thumbs down when he reaches base.

When he slugged another three-run shot in Thursday's game at Yankee Stadium, just about everyone in the Yankees dugout saluted him with the gesture as he rounded the bases.

When asked about that, Dunaier laughed.

"How about that," he said. "I should charge them a licensing fee or something. Hey, I've got to make some money off this, too. He's making his money. I need to make some, you know."

Was Dunaier kidding? Being serious?

"A little of both," he said.

Dunaier said he's just happy he "wasn't doing anything stupid."

"Sometimes they get pictures of fans sleeping at the game and they poke fun a little bit," he said.

He added that he sees it "as all in good fun. I'm getting a big kick out of it."

Though, he said, that while his friends have helped make it enjoyable, he hasn't appreciated remarks he's seen online that have ripped him for his appearance.

Dunaier said he grew up a Mets fan and loves Michael Conforto. His distaste for the Yankees isn't just simply a rivalry thing, though.

Dunaier called the new Yankee Stadium a "fake, soulless structure that was built on a parkland stolen from the neighborhood."

Dunaier said he felt he was treated badly by Yankee Stadium security the last time he attended a game in 2012. Dunaier said an overzealous security guard yelled at him when he politely asked the guard to move while he was trying to take a picture.

"if that's the kind of attitude the Yankees have toward their customers, I have to feel sorry for the people who go to Yankee Stadium," he said.

Another thumbs down from Thumbs Down Guy.
