“The Flight Attendant’s” Kaley Cuoco and Zosia Mamet have revealed the meaning of a new shared tattoo, stating it was inspired by the first day they met. During a Q&A with E! News Daily Pop, the co-stars said they liked each other during their chemistry read for the HBO Max series that Cuoco gave Mamet a quick “boop” tap on nose.

“It became a thing, and then we did it all the time,” Kaley Cuoco explained, adding that in April 2022, the two got the term “boop” tattooed on their forearm.

“Many years ago, @zosiamamet, I ‘booed’ you. It’s great that we’ve made it official. Thank you for the perfection, @ar.bel,” Cuoco captioned a photo of their teeny-tiny tattoos on their arms.

“It all started with “boop” @kaleycuoco,” Zosia Mamet captioned the photo on her Instagram account. “It’s just right.” Thank you, @ar.bel, for this lovely permanent reminder. I can not imagine what life would be like without you.

“Now people are bopping each other,” Cuoco remarked about how popular the sweet sign of affection has become. I believe we’re generating quite a fuss.”

“Did you hear about how ‘Fetch’ didn’t work out?” “‘Boop’ is happening,” Mamet continued, recalling a line from the film “Mean Girls.”
