What is oh my lanta?

"Oh my lanta" is an expression often used to convey surprise, astonishment, or excitement. It gained popularity through its use in pop culture, particularly in the 1990s sitcom "Full House." The character D.J. Tanner, played by Candace Cameron Bure, frequently used the phrase, which contributed to its widespread recognition.

The phrase itself has roots in a euphemistic reference to the antacid brand "Mylanta," and originally surfaced as a way to express amazement or shock without using stronger language. It has since become part of colloquial speech, especially among fans of the show.
