Enrevesado/alrevesado

[Glen]

Which one is more commonly-used for saying complicated/difficult/involved/hard to understand, etc?

I only use enrevesado. It implies something to be cryptic or extremely complicated; also to be unapproachable from an intellectual point of view.

Alrevesado sounds vulgar to me (in fact I'm hearing it "alrevesao"), as if something is upside-down or topsy-turvy and figuratively the speaker is trying to convey the notion of enrevesado.

That helps. Thanks!
