⇨ all of a tiswas; all of a tizwas; all of a tizzyadjective in a state of panic or excited confusion. Probably a Royal Air Force coinage; from TIZZ; TIZZY (a state of panic), contriving what appears to be an etymology by amending the source-word to 'tiswas', a combination of 'it is' and 'was', suggesting a play on the earlier colloquial phrase 'not know whether you are coming or going' (to be in a state of confusion) UK, 1984
