Oh la la has long been used in English-speaking humour as a shorthand for flirtation, surprise and admiration, borrowed from French and familiar from cartoons, comedy and everyday speech.

Creators keep returning to it for fashion reveals, dating jokes and playful teasing, where a single knowing phrase can set the tone faster than a longer explanation.
