porro
/ˈporo/ · B2 · adj
stupid
sounds like 'porro' = a thug who acts dumb: stupid, and a campus-attack goon
Porro comes from Spanish 'porra' (club, cudgel). A porro is someone who wields a club, hence a thug. Calling someone porro as an adjective suggests they are thick-headed, like a blunt club. In Mexico, porros are violent groups used against student protesters.
