I am fond of "countertautology" which I believe I picked up from Makinson's Topics in Modern Logic.

Dear all,

The standard English word for sentences (or propositions)
that are always true is 'tautology'. Is there a word for
sentences that are always false? (No, I don't want to hear
'contradiction', for that is defined as a sentence of the
form 'p and not-p', or something logically equivalent to it,
and therefore is a syntactical notion.)
