corrérsela

A colloquial, regional expression (common in Mexico and parts of Latin America) meaning to have a great time, party hard, or go all out — "nos la corrimos toda la noche" (we partied all night). Very informal, spoken register only.

• Nos la corrimos en la fiesta hasta el amanecer. — We partied hard at the party until dawn.
• Se la corrieron en las vacaciones sin pensar en nada más. — They lived it up on vacation without a care in the world.
• Vamos a corrérnosla este fin de semana. — We're going to go all out this weekend.

This is slang tied to specific regions and can carry other, more vulgar connotations in different dialects — it's not something to use in formal or unfamiliar company without knowing the local register first.

Often confused with correr.
