To ruin something deliberately or through inexcusable carelessness, leaving it beyond any repair. In Colombia and Venezuela tirarse algo means making it so bad there's simply no way to fix it anymore.

In Venezuela and the Caribbean, someone who acts like they're on the same level as someone above them — overstepping their rank without having earned it. Disrespectful overfamiliarity.

A vulgar, crude person with no social graces who demonstrates it loudly in every situation. In Colombia the chusquero always proves the point with their actions no matter what the setting is.

A mischievous, cheeky person of questionable conduct who always ends up in some kind of trouble. In Colombia the tunante is the lovable rebel who pulls pranks and somehow always gets away with it while smiling.
