This is a phrase uncommonly used amongst young males where one male points out to the other that he can see his "jonny," at this point the other male claims that it "pays to advertise" and waves to the ladies.
Guy: I can see your dick.
Guy #2: Pays to advertise.
Guy: not when you are that small, jesus man get an operation that is just sad.
