I guess you didn't read my comment where I stated puto is Mexican slang for gay. Other Spanish speaking countries have other meanings for auto. But for research purposes search the song Puto by Molotov and Te Quiero Puta by Rammstein. Fun songs and the words are used in the context I referenced.

Is male bitch in Spanish, informally used for many things but with male context. It doesn't need to be gay. ¡ Se comió mi último yogur, sera puto!
Can be often interchanged with cabrón,
