In soccer, a player who lacks any sense of the game, has little to no skill, and plays simply through brute force and athletic ability alone. "Goons" usually try to play by slide tackling as often as possible.
This player will also lack any "soccer swag" and can usually be spotted from his outfit. A typical goon uniform will consist of Wal-mart brand cleats, overly big shin-guards with ankle protectors and a baggy jersey. Sometimes, but not always, can also be spotted with "sweet spot" lace holders, rec-spec glasses, and basketball head bands.
These players usually have had no training in the sport outside of their high-school or recreational teams. Most "goons" also will deny the fact that they are one repeatedly.
Peter: "Yo man, we just beat FC Burn this weekend 5-0. Team was full of goons"
Frank: "Yeah dude they suck dick, kid's were all over the field slide tackling left and right."
