To be physically attractive, to have a face or body that turns heads. Used casually among friends in Mexico, Spain, Argentina, and Colombia. Said openly and without ceremony, though telling someone directly can come across as very forward depending on the relationship and tone.

A chronic heavy drinker, beyond just someone who got drunk at a party. In Argentina, curdela implies someone who has a long, established relationship with the bottle. The tone mixes humor with a hint of pity, more loaded than simply saying "borracho."

A pre-game gathering to drink alcohol before heading out to the actual party in Argentina, Chile, and Uruguay. The previa is often more fun than the actual event, cheaper drinks, better music, and your closest friends.

A person living in their own fantasy world who refuses to accept reality. Straight from English, it's the go-to Gen Z insult for anyone whose self-perception is wildly disconnected from the truth.

Someone who complicates everything unnecessarily, takes forever to get to the point, or wraps simple things in layers of excuses and detours. Used in Argentina and Uruguay. The irony is that milonguero comes from milonga (tango dance hall), but in this sense it refers to someone who dances around the subject instead of just saying what they mean.

Unnecessary detours or beating around the bush instead of getting to the point.

A misleading headline, title, or thumbnail designed to make you click by promising something spectacular that never actually appears in the content. The internet's oldest trick, and everyone still falls for it regularly.
