A term originating out of the suburbs of Montgomery County, Maryland, where there is a police officer for every man, woman, child and dog.
Scaredboy refers to an individual who has a deep fear of authority, especially that of law enforcement.
However, scaredboy does not in any way refer to a cowardly person. In fact, a Scaredboy is more fearful of police showing up due to a fight than being in the fight itself.
"I hate chiefin' with that Scaredboy, he always gets me nicked."
