Surface Forms
Morphology
The meaning is directly compositional: 'act' (behave) + 'like' (in the manner of) + 'dumbo' (a foolish person) yields 'behave foolishly', so a B1 learner who knows the constituents can infer the sense. The pattern is a simple simile common across languages; although 'dumbo' is slang and mildly insulting, that lexical register does not prevent transparent understanding of the overall phrase.
Etymology
Act like a dumbo may come from the cartoon elephant Dumbo, who looked clumsy and a bit silly, and to act like him is to copy that foolish behavior, so the phrase means 'to behave in a foolish or silly way'.
