3SM

Third String Motherfucker. One who plays behind the first and second string players. Generally has significantly lower abilities and is only used when a team doesn't care if they win or lose.

Sports: Why are we losing so badly? Oh yeah we have all of our 3SMs in.

Business: That 3SM literally couldn't give away a free product.
