WATCH: Gordon Ramsay tries Girl Scout cookies for the first time

British celebrity chef Gordon Ramsay is in the dog house for dissing a beloved part of Americana.

The host of Fox's "Hell’s Kitchen" went on "Jimmy Kimmel Live!" last night to promote the current season of the TV cooking challenge series and had the chance to try Girl Scout cookies.

Forewarned by Kimmel Girl Scout cookies are "sacred territory" of Americana -- right up there with the American flag and Willie Nelson--it still doesn't stop the bad boy chef from spitting out Thin Mints after taking a bite.

Ramsay was presented with three cookies: Tagalongs (Peanut Butter Patties), Samoas (Caramel Delites) and Thin Mints.

Not only was he turned off by the look of the chocolate peanut butter patties, he was fairly blase about the Tagalongs' taste (for real).

"Visually they look like dog biscuits," says Ramsay of the Tagalongs, before admitting that "they're OK."

For the Samoas, he says they're "a bit weird," of the caramel and coconut combination. (okay, we get that.)

When it came to the Thin Mints, you may want to shield your eyes at this part in the video.

"These are my favorite ... now what I will do is I put these in the freezer and you pull out a sleeve and you eat all of them in one sitting," said Kimmel.

Not going to happen, judging by Ramsay's reaction. He spat them out.

"It's like a cheap, half-rate dinner mint," Ramsay said with a scowl on his face.

"Gordon Ramsay's visa just expired," says Kimmel with a laugh.
