'PissG' - is a French football club who think signing created players is the only option to stay on top. When they sign a big player they totally become dependent on that player. They think he will carry the ball from defence and score a goal and also defend from conceding goals. Their fans have ZERO respect to the respected players. Overall the word 'PissG' indicates a person who always relies on something or somebody to do a work for them and then disrespecting them later even if he worked well.
