A Spanish word that literally means "miscarried" ("malparto" means "miscarriage"), but is often used as an insult.
In practical usage, it is very similar to the English "bastard", seeing how the Spanish term "bastardo" is seldom if ever used as an insult by native speakers and means, very literally, an illegitimate child.
Call someone "miscarried" in English, or "bastardo" in Spanish, and they'll look at you funny. Call them a "malparido" or a "bastard" and they will take offense.
Ese flaco es un malparido del orto
(Literal: That guy is miscarried through the a**)
(Paraphrased: That guy is one rat bastard)
A spanish curse. Literal translation is "ill-birthed". Usually directed at someone (unlike "fuck", which can be directed at no one in particular). Pretty much means "son of a bitch" in English.
