A couple of heards:

[W Brewer]

WG: <<"shat" used as the past of "shit">>
WB:  Not to digress, but has anyone run across <shy-poot>? (If so wipe yer
feet!) It comes from somewhere deep in the recesses of my memory. Seem to
recall my father (*1925) using it as a quasi-risque' euphemism for
'bullshit, nonsense': <<You're fulla shypoot!>>. As if <shite> + infixed
<poo(poo)>.
