agringar

Colloquial, mostly Latin American: to become gringo-like — adopting the habits, accent, or manners associated with (usually) US Americans, almost always used with mild disapproval or teasing about someone losing their local ways. Agringado/a is the far more common form, as an adjective.

• Se agringó tanto que ya casi no usa modismos locales. — He's gotten so gringo-fied he barely uses local slang anymore.
• Sus primos se agringaron después de vivir en Texas. — Her cousins picked up gringo ways after living in Texas.
• No te agringues, no olvides tus raíces. — Don't go gringo on us, don't forget your roots.

Using agringarse as a neutral, purely geographic description — it almost always carries a value judgment (usually gentle mockery or mild criticism) about cultural assimilation, not a neutral fact.

• expression Agringado — A widely documented term in Latin American sociolinguistics and literature for someone who has taken on US/Anglo customs, accent, or Spanish peppered with English — commonly used with derogatory or ambivalent overtones about cultural assimilation and identity.
