fair do's

a frequent misinterpretation of much older common expression 'fair deuce' meaning fair point, good play (as in tennis), often used informally to recognise good (verbal) comebacks.

Hard to distinguish "do's" from "deuce" particularly given regional and american accents which pronounce "u" as "oo"
