Puerto Rico
The song's slang relies on the Puerto Rican habit of repurposing ordinary verbs and nouns for social meaning ('frontear', 'dar la vuelta', 'fiarse de'), and on dropped final consonants in casual speech ('ve'' for 'ves', 'fía'' for 'fías'). This trimming of word endings is a hallmark of the rapid, melodic cadence of island reggaeton vocals.
