A term often used by bean eating wetbacks to describe the worker drones of their society. Mamuscias, or Mamus as they are often called are easily defined by their red curly hair, distorted facial expressions and inability to actually speak like a spic should.
Fuck me, that Mamuscia just can't get his fucking shit together. What a mamu!
