A Mexican-American who engages in patterns of overconsumption, self pitying and general vapid lifestyle much more common among white folk who aspire to be of a higher socio-economic class than they actually are. Portmanteau of bougie (i.e. bourgeois) and Chicano.
Did you see Cuauhtémoc's pics on Facebook with his new beemer, beach house and bimbo? He is such a Bougicano.
