What is Spotter?
1.
A criminal-accomplice whose job is to watch out for incoming policemen while his friends commit a crime (usually drug dealing, burglaries, safeguarding supply houses, etc). Spotters are basically human alarm systems that criminals use to warn them when the cops come near. They usually stand on a corner to get a better vantage point and to give their friends plenty of time to run away, flush the drugs, etc. The warning is usually a shouted code, but can sometimes also be visual; modern criminals now use cell phones. Often times, spotters are juveniles who can't be effectively punished by law for aiding in a felony.
Hello, mama? I'm in jail. The popo arrested me for chillin' on the same block where some dealin' was going down. They say I was spottin' and they be chargin' me as an accomplice.
2.
A military term for some one who sits and waits (usually fairly concealed) for something notable to come along and then informs the rest of his group.
