In Puerto Rican dialect, charro(or charra if female) is both a noun and an adjective used to describe someone or something that is pathetic or someone who is a jackass(i.e.someone who makes an ass out of him/herself)

A person who has no sense of dignity is considered a charro and something that's tacky or garish can be considered charro as well. It's not a very offensive word but it can be insulting sometimes.

Another derived form of this word is called charreria(jackassery)

1.A Charro is a traditional cowboy of central and northern Mexico (The word itself is not used as an insult in traditional Mexican dialect)
2.The traditional charro is known for colorful clothing and participating in charreadas, a type of rodeo
