If you really want to show pride, substitute Puertorriqueño(a) with Borinqueño(a).
Ex.: Ese señor es definitivamente Borinqueño. = That gentleman is definitely Puerto Rican.
¡Vaya Boricua! or ¡Vaya Puertorro(a)!: roughly translates to "Yo hommie from the island"
Actually I was looking at the clock on the wall behind you so pike down cause I wouldn't touch a man whose been with you."
