Jarana Spanish

paja

Short answer

In Lima, "paja" means great, brilliant — in Peru only. The register is coloquial — fine among friends, out of place in a job interview or anything written to an institution. The standard Spanish equivalent is "genial, buenísimo". In use: ¡Qué paja tu proyecto!

Read the region line carefully. In Peru this is straightforward praise. In Spain and much of Latin America the same word is vulgar slang, so it does not travel — one to understand at home and leave behind at the border.
