Morphology

be + a + booby

The meaning is directly compositional: 'be' (to have a state) + 'a' (article) + 'booby' (a foolish person) yields 'to be a fool' or behave foolishly. This copular construction is a common, cross-linguistically transparent pattern, so a B1 learner who knows the constituent words would readily infer the MWE meaning.

Etymology

Be a booby comes from the word booby, a name sailors gave to a clumsy sea bird that looked friendly and easy to catch. Because the bird seemed 'stupid', people began to call careless people boobies, so be a booby means 'behave in a foolish or silly way'.
