daffier

Increasingly off-kilter

Daffier is the comparative form of daffy, meaning sillier or more scatterbrained.

Someone acting daffier than usual is being goofier or more absurdly eccentric: She got daffier as the night went on.

The word carries affection rather than criticism—daffy people are endearingly foolish, not genuinely stupid.
