Charlie Brown = Bad Cocaine. This could be either because it gives a bad experience, is contaminated, or just not very good. Derived from the slang from cocaine - charlie, and the peanuts character Charlie Brown.Often abbreviated to CB.

Ancient CB* term from the late 1970's meaning "prostitute in area." Experienced prostitutes would travel three-or-four to a car equiped with a CB radio and/or police scanner and cruise truck stops at night. During the height of the CB craze in America, some truckers would stay-up all night on their CB's talking and jabbering in their strange CB codes. The prostitutes would cut-in on the conversations announcing "commercial comfort" had arrived. This would then be followed by hand signals or flashed headlights indicating who their next "customer" was.

The term "commercial comfort" was last heard on the dying CB airwaves as late as 1998, just prior to affordable cell' 'phone plans and the Internet took over.
