Morphology

act + like + a + cretin

The phrase is fully compositional: 'act' (behave) + 'like' (similar to) + 'a cretin' (a foolish person) yields the meaning 'behave foolishly' directly from its parts. The 'act like X' construction is common cross-linguistically and follows a standard simile/comparison pattern, so a B1 learner who knows the constituent words would readily infer the meaning.

Etymology

The phrase act like a cretin comes from the old word cretin, once used for people with a serious health condition that affected their thinking, and later used as an insult. So act like a cretin now means 'to behave in a very foolish or stupid way'.
