Spanish for small.
Is also the nickname for a certain individual who, despise his good looks and intelligence, wasn't as tall as the rest of his class, or was in fact the shortest boy in his last year of elementary school (kids can be so cruel).
Chiquito is used by Mexicans as a word meaning ass hole not like the insult asshole but the literal ass hole because chiquito means tiny and your butt hole is a tiny hole.
