The name for the Spanish lime fruit, known as mamon in the rest of Venezuela, used specifically in the eastern part of the country. It is a small, round fruit with a green rind and gelatinous pulp that is eaten by sucking it off the pit. (The eastern region refers to states like Sucre and Anzoategui).
I bought a bag of really sweet macos at the Cumana market to eat during the trip.

That program is garbage, it has way too many macos.
A knock-off or fake item that is presented as being original or high quality (literally, a maco is a toad, used metaphorically for something deceptive or defective).
Don't buy those pants because they might be a Maco.
A woman with a prominent or bulging vulva, or the protruding vulva itself (the word literally means toad, used as an analogy for the bulging shape often seen through tight clothing).
