Polo

Literally means self-immolation, but used colloquially to mean accepting punishment or blame on someone else's behalf. The dramatic gap between the literal and idiomatic meaning is part of the expressive effect.

Used as a command ('lárgate' = get out) or reflexively ('me largo' = I'm out of here). More forceful than 'irse' and always implies the departure is unwanted or abrupt.

Appears in fixed phrases like 'me cago en mi puta vida' (an expression of extreme frustration). The phrase is idiomatic and ritualized; its literal meaning is irrelevant in context.

Common as an insult meaning a stupid or contemptible person. Slightly less frequent than other insults in this register but clearly understood.

Literally means to crush or grind, but reflexively it describes excessive self-criticism or guilt. 'No te machaques' is a common reassurance meaning 'don't be so hard on yourself'.

Despite containing a vulgar word, this phrase is used to express genuine enthusiasm or approval. The tone is almost always positive and energetic, not aggressive.

One of the most frequent intensifiers in informal speech. Can precede nouns to add frustration ('el puto tráfico') or, less often, admiration ('es un puto genio'). Context determines tone entirely.
