In Puerto Rico, someone who is a wannabe guaynabicho or guaynabicha.
Guayanabichos tend to be of higher class, no lower than middle-high. However a number of people from lower classes strive to appear higher than they are and imitate the affectation, manner of dress, politics, and other accouterments of guaynabichos.
This fools no one, specially not the real Guaynabichos, who take advantage of them and turn them into useful fools.
Port-manteau of "guaynabicho" and "wanna-be".
"You are such a guayna-be, wearing counterfeit Crocs and fake Lacoste"
"Only a guayna-be would vote for that guy"
