Alero
Close friend, mate — the one who stands at your wing, or under the same eaves.

Hear it in context
Te presento a mi alero, crecimos en la misma cuadra.
This is my mate — we grew up on the same street.
¿Qué ondas, alero? ¿Cómo te ha ido?
What's up, mate? How have you been?
Es buen alero: me prestó pisto sin preguntar para qué.
He's a good mate — he lent me money without asking what for.
What It Actually Means
Alero is a close friend — the sidekick, the constant companion, the one who is simply always there. It carries more loyalty than amigo and less intimacy than family, and it implies shared history: an alero is someone you have accumulated years with, not someone you met last month. It works both as a label (mi alero, es buen alero) and, more often, as a vocative shouted across a street.
Where It Comes From
Two accounts, both plausible, neither settled. The standard one derives it from ala, wing — your alero flies at your wing, the way a wingman does in English, which is a striking coincidence of metaphor rather than a borrowing. The other takes the ordinary architectural meaning: el alero is the overhanging eaves of a roof, and the friend is the person sheltering under the same one. Honduran speakers will offer you either with equal confidence. The wing version is the more widely repeated; treat both as folk explanation.
How Natives Use It
Informally and warmly, male-leaning but not male-only, throughout Honduras and across the border into Guatemala and El Salvador, where it does the same job. The affectionate diminutive alerito exists. It competes at home with mano (from hermano), maje and chero — a crowded field, in which alero is the one that most clearly means “old friend” rather than “bloke”.
Common Pitfall
Do not use it on someone you have just met. Alero asserts a closeness, so applying it to a new acquaintance sounds either presumptuous or as though you want something. Save it for people who would already describe you the same way. And be ready for the register siblings in every other country — pata in Peru, parcero in Colombia, cuate in Mexico — none of which travels to Honduras.
