The male chimera
Since ancient times, even when homosexual behavior was normalized, consideration was not the same for man who fucked another man (the top) that for man was fucked (the bottom). This different social consideration has allowed self-identified heterosexual men, were able to unleash their desires from past to present, without reducing the social acceptance and without much repentance.
For these men, in Spain, was created the famous Mahomet's law: as faggot is the top as the bottom (La ley de Mahoma, tan maricón es el que da como el que toma), and probably with a double message, the first is the obvious, and the second is the reference to the Muslim world, where it is likely that, given the difficulty of having sex with women, sex between straight men and homosexuals, is more widespread and more known. After fucking, the different consideration of the role they occupy, allows them to think of themselves as so much males, that they can fuck whatever, despite the fact that these societies are not very gay friendly.
For this kind of males, in Peru have a word: mostacero.
The first and universal meaning of mostacero is the bottle containing mustard sauce, and it is from this image, the mustard dripping down the spout of the bottle, when it makes the jump to the eschatological meaning. Make no bother, but we're talking of shit, feces, poop ... or whatever you want to call, for their similar colour.
The mostacero is a heterosexual man and beyond, is the male, rough looking, virile, manual worker, sailor, soldier, welder, agro-man, etc, who gets horny with the butt of the apprentice. We can complete the profile with the essence of patriarchy: male chauvinism, sexism, homophobia, xenophobia, etc. This type of man also is in great demand among fags seeking "real real men". The mostacero cock, mustard stained, reveals the slang meaning of the word. Synonym of mostacero is the word chacal, meaning jackal, although depending on the area of Latin America in which we are, mostacero, chacal and its derivatives as chacalote, maintain their relative meaning to gay sex but varying towards the subject of pederasty or male prostitution, like the case of Mexico and Chile.
