What does flub mean?
'Flub' is an informal English word meaning to bungle or botch something, most often a spoken line, an answer, or a rehearsed action that was expected to come off smoothly. An actor who forgets or mangles a cue has flubbed the scene; a politician who garbles a prepared remark has flubbed the delivery. It also serves as a noun, naming the resulting blunder itself: 'a minor flub.' The word emerged in American usage in the early twentieth century, apparently in theatrical circles, and its tone is deliberately light-hearted — a flub is a small, usually recoverable mistake made in public, not a grave failure. That gentle, forgiving quality makes the word useful for describing human error without harsh judgment, which helps explain why it remains common in commentary on performances, broadcasts, interviews, and speeches on both sides of the Atlantic.
To bungle or botch, especially a line, answer, or rehearsed action performed in front of others.
"She flubbed the toast by calling the groom by the wrong name."
A blunder or badly executed attempt, especially in speech or performance.
"The broadcast contained an embarrassing flub during the weather report."
Standard countable plural for the noun form.
"The rehearsal was riddled with flubs, but the opening night went flawlessly."
Born backstage in American show business, 'flub' became the go-to word for every dropped line and fumbled moment — even presidents get accused of it on live television.

Etymology of flub
'Flub' appears to have originated as an American slang term in the early twentieth century, with early use associated with the theater, where fluffed or forgotten lines were everyday hazards. Its exact origin is obscure, and lexicographers generally treat it as a expressive slang coinage of uncertain derivation rather than tracing it to a specific earlier root. It developed a noun form alongside the verb, and related playful compounds such as 'flubdub' appeared in the same era.
