Al pedo
Pointless, in vain — or idle, with nothing to do. Not the same as "en pedo".

Hear it in context
Fuimos hasta allá al pedo, estaba cerrado.
We went all the way there for nothing, it was closed.
Estoy al pedo, ¿querés que te ayude con algo?
I've got nothing to do, want me to help you with something?
No discutas con él, es al pedo.
Don't argue with him, it's pointless.
Tenés un montón de cosas al pedo en ese cajón.
You've got a ton of useless stuff in that drawer.
What It Actually Means
Al pedo covers two related ideas: something done in vain or pointlessly (“viajamos al pedo” — “we traveled for nothing”), and the state of being idle with nothing to do (estar al pedo). Literally it involves the word for “fart”, but Argentines use it so constantly that the vulgarity has worn down to a mild edge — think “for sod all” rather than anything stronger.
Don’t Confuse It With “En Pedo”
This is the trap: the same noun builds several completely different expressions, and the preposition carries all the meaning. En pedo means drunk (it has its own entry) — and “¡ni en pedo!” means “no way!”. Al pedo means pointless or idle. Mix them up and “estoy al pedo” (“I’m free / doing nothing”) becomes “estoy en pedo” (“I’m drunk”) — a memorable error to make with your Argentine in-laws.
Common Constructions
Hacer algo al pedo — to do something in vain. Estar al pedo — to have nothing to do. Ser al pedo — for a thing or action to be useless: “es al pedo insistir” (“there’s no point insisting”). You’ll also hear al pedo describing useless objects taking up space.
Register Warning
Mildly vulgar. Fine among friends, everywhere in casual porteño speech, but not for a job interview or your first meeting with someone’s grandmother. The clean substitutes are en vano (in vain) and sin nada que hacer (idle).
