Kaley Cuoco and Zosia Mamet tell why they have the same tattoos and what they mean

Kaley Cuoco and her best friend Zosia Mamet from "Stewardess" revealed what their matching tattoos on their arms mean. The actresses explained that they got them inspired by the first time they met.

They really liked each other during a script reading, and Cuoco gently poked Mamet on the nose saying: "Boop."

"It became a thing, and then we did it all the time," Kaley said.

The same phrase was in the movie Mean Girls when one of the heroines said: "Boop’ is happening." That's the word they had tattooed on their arms as a symbol of their friendship, Page Six writes.
