Definition & Meaning of "flipping"in English

What is the origin of the exclamation "flipping" and how is it used?

Flipping is an exclamation used alone to express frustration, surprise, or mild anger. It appeared in British and American English in the mid-20th century as a euphemistic substitute for stronger swear words, especially "f—ing," allowing speakers to convey emotion without vulgarity. People used it in everyday speech, cartoons, and media aimed at general audiences. Today it is inoffensive, casual, and mildly emphatic, often signaling irritation, astonishment, or emphasis in a lighthearted way rather than serious anger.
