That I be fals; and if I do that lak,
Do strepe me and put me in a sak,
And in the nexte ryver do me drenche.

– Geoffrey Chaucer

The Canterbury Tales, The Merchant’s Tale. May shamelessly and barefacedly assures January that she will not be false to him.

She is being completely dishonest, as she is exchanging love letters with squire Damian whom she plans to have sex with.
