A person who is 'CHIA' like. This person will make the most outlandish excuses for his actions. ie: "the pen wrote it down wrong." or "I entered it right, the computer must of changed it."

A person who will make mistakes and will blame everyone else for his incompetence.

He also may flake.

"El Retardo" is the name of a fictional, Mexican vigilante that seeks justice but always fails becouse of the mistakes he makes which are results of the fact that he is mentally slow. (retarded)

Although, the phrase "El Retardo" is most of time used to describe an indevidual with very low intelligence by comparing that person to that super-hero.
Even though El retardo tried to stop the criminal, he failed becouse he forgot who he was after in the middle of an intense chase

"You are dumber than El Retardo, you know that?"

"Oh no, look out! It's El Retardo!Beware of his low intelligence!"
