the police are often referred to as heat, some people call it "bringing the heat" to be noticed by police. This phrase is usually used in a drug deal situation, and someone who is considered a heaty or heat score is an undesirable customer. Also used to describe situations where you are attempting to avoid detection in your dealings, and a police/authority figure gets close...this is a heat score

heat as in police, score as in informant... though unsure as it might mean become a target as a treachorous fink

but definately a good way to earn a broken kneecap if you rat somebody out on the streets by drawing attention to them

taking a guess from the context it was used in when I heard it on the west coast of canada and wouldn't mind knowing more about the proper definition
