Morphology

a + bit + loony

The meaning is directly compositional: 'a bit' (a small amount) functions as a degree modifier for 'loony' (crazy), yielding 'slightly crazy/silly.' This follows a common adjective modification pattern in English (and parallels in many languages), so a B1 learner who knows the constituents can readily infer the MWE meaning.

Etymology

A bit loony comes from an old idea that the moon could make people act strange; the word loony is a short form of 'lunatic', which was linked to the moon. So a bit loony means 'a little crazy' or 'a little odd'.
