a) A superficial, obtuse and flat person with no character. Ronnos are always ready to share easy insight when you need it and don't often circle around difficult subjects that require depth of character, for they don't have any. Ronnos often do things for no reason at all as it wasn't written properly in their character. These kinds of people can be useful babysitters and great at captivating your children.

b) Synonym for bully, both the noun (one that is of Make-A-Wish quality) and verb.
