apajuilarse

A rare Salvadoran and Honduran regionalism meaning to feel sad, dejected, or afflicted, and in Honduras also to lose one's nerve or become timid. It derives from paují/paujil, a wild, notably shy and skittish turkey-like bird found in the region's mountains, giving the verb its sense of shrinking, cowering sadness.

• El niño se apajuiló después de perder el partido. — The boy got dejected after losing the match.
• No te apajuiles por un solo fracaso. — Don't get discouraged over a single failure.
• Se apajuiló y no quiso hablar con nadie el resto del día. — He got despondent and didn't want to talk to anyone the rest of the day.

Expecting apajuilarse to be understood outside El Salvador and Honduras — it's a strongly regional word, tied to a specific local bird, and unfamiliar to most other Spanish speakers.
