Anthony Edwards' bank account just got shafted by the NBA ... with the Minnesota Timberwolves hooper getting hit with a $50,000 fine for telling a Lakers fan his "dick bigger."
The league just announced the punishment on Tuesday ... saying the 23-year-old All-Star directed "inappropriate language" toward a fan -- as well as an "obscene gesture."
The incident went down with less than five minutes left in the third quarter of the Wolves' 117-95 Game 1 win over Los Angeles .
