A homeless person who is addicted to inhaling shoemaker's glue and survives by begging (clefa is a common name for the contact cement used as a cheap inhalant drug).
That man is a CLEFERO, that is why he lives under the bridge.
A destitute or insignificant person, a nobody. (A rulo is a cheap type of cooking banana in the Dominican Republic, and the term suggests the person is so poor they can only afford basic staples).
An evolutionary throwback with a body similar to a primate or prehistoric creature. He shows up uninvited in random places, constantly looking for a way back to Monodia, his hometown. He is known for having white, almost transparent skin, a short stature, and making strange sounds when he feels threatened. (Monodia is likely a wordplay on mono, the Spanish word for monkey).
