Cayetana and Valerio

Describes performing for social show rather than with genuine intention. Implies insincerity or playing a role for others' benefit.

Placed after a noun to express that something is of very poor quality or deeply unpleasant. Very common in informal speech as a general negative intensifier.

Fixed phrase. 'Darle la razón a alguien' means to concede that they are correct, or to act in a way that vindicates them. The negative form, 'no darles la razón', means refusing to let them win.

Very common idiomatic use of 'venir'. The subject is the thing that suits, not the person. 'Me viene bien' means 'it works for me / it suits me'.

Idiomatic euphemism for snorting drugs. Literal meaning is transparent, but the idiomatic use is specifically tied to drug consumption in casual speech.
