@boisdevache@guineapig.party EXACTLY but some people punctuate it that way and they are Wrong.
(i think it might be more of a mid-atlantic/yankee thing because then you are thinking of the contraction as "ya + all" not "you + all", and while 'you' does get shortened to 'ya' down here, in the deeper south it tends to be a different sort of vowel sound than starts 'all' - more like 'yuh' - but i ain't a linguist lol)
