pirobo: it's an slang expression of general knowledge, I would say its's used in most colombian cities, to connote -only to males- a low life person with very questionable values in regards to interprete psychological, philosophical, moral and socially most accepted trends, and conduct in his every day behavior. He is not precisely a vernacle of nobility, he has a defective thought sistem, however well defined to fulfill his intentions. he could be slay, false, psychotic, normal, with abilities, act with relaxed indifference, delusional, a trickster, and maquiavelian. So it is more than the "femme' part in a male homosexual relationship.
Used in Colombia as well
"that pirobo is untrusting and he is a nuisance to having to deal with."
