A 'palooka' is an informal, often derogatory term for a clumsy, inept, or naive person, especially a boxer who lacks skill. It implies someone is a bit of a loser or a pushover. Think of someone who is easily fooled or outmatched in a competition. It can also describe someone who's just generally awkward or lacking in confidence. It's not a very flattering term, suggesting a lack of competence and street smarts.
