1 Henry VI: giglot

From William Shakespeare’s Henry VI, part 1 (IV: 7):

JOAN LA PUCELLE:

Once I encounter’d him, and thus I said:
‘Thou maiden youth, be vanquish’d by a maid:’
But, with a proud majestical high scorn,
He answer’d thus: ‘Young Talbot was not born
To be the pillage of a giglot wench:’

giglot: A wanton; a lascivious or light, giddy girl.
