I agree SS - take some deep breaths and call your son in another room and tell him it's time for his friends to leave. Next time this is what I would do - no friends are allowed over until all his homework and house chores are done. Limit the amount of friends and how long they can stay. Set boundaries with what meals they will be eating at your house. Tell him he should do all the cleaning - not just piling them in the sink. He needs to clear it with you before the guys come over. If homework isn't done, then no friends over. Be firm and stick to it. I have no problem when my daughter has her friend over to say "it's time too leave girls" or I tell my daughter to tell them. This is your house ((SS)) and you can express yourself with out exploding.
