The Cyber House Rules

Literally means 'trash can' or 'garbage dump', but used colloquially to call a place filthy or depressing, not just physically dirty. The insult is about overall quality and atmosphere.

Used in Latin American Spanish to describe the act of successfully flirting with or attracting someone. Not compositional from 'ligar' in its standard dictionary sense.

Fulana (feminine of fulano) literally means 'so-and-so' but in many contexts carries a dismissive or derogatory tone toward a woman, implying she is of questionable character. Tone shifts heavily with context.

Literally 'to scrub', but used idiomatically to mean showing off or gloating in someone's face. The phrase 'refregar el éxito' means to flaunt success at someone who has less.

Literally 'like a little horse'. A fixed phrase used across Latin America to describe riding on someone's back, typically a child on an adult. Not guessable without knowing the idiom.

Can mean a gang in the criminal sense, but very commonly used in a neutral or affectionate way to mean a close group of friends or a crew. Context determines whether the tone is neutral or negative.
