Luego luego
Right away, immediately — doubling flips 'later' into 'at once'.

Hear it in context

You can tell right away that you're a foreigner.
—¿Vas a venir? —Sí, voy luego luego.
—Are you coming? —Yeah, I'll be right there.

What It Actually Means
In Mexico, single luego means “later” or “then” — but say it twice and the meaning flips. Luego luego means “right away”, “immediately”, and by extension “right at first glance”: “Luego luego se ve que es caro.” It’s one of Mexican Spanish’s neatest tricks: repetition doesn’t add delay, it removes it.
The Rule That Matters
Reduplication as an intensifier is a productive pattern in Mexican Spanish: casi casi (“this close to”), el mero mero (“the big boss”). Doubling narrows and sharpens the meaning — and luego luego is the doubled form you’ll hear most often, in everyday speech from Tijuana to Mérida.
Where Textbooks Get It Wrong
Textbooks translate “immediately” as inmediatamente or en seguida — correct, but stiff in casual Mexican conversation. Meanwhile the famous ahorita promises “in a moment” with legendary elasticity (it can mean anywhere from now to never). Luego luego is the expression that actually commits: when someone says it, they mean now.
Common Pitfall
The trap is hearing it as “later, later” — the exact opposite of what it means. Keep the pair straight: if the plumber says he’ll come luego luego, stay by the door; if he says luego, make other plans for the afternoon.
