Ping Ping (or FPS)

My friend was proposing that you can ping your ping in chat. He plays often alone, and he sometimes doesn't like this game purely because people call him bad. The issue is his computer broke, so he is using my old one, and lags a bit in game sometimes. For the same goal, neither of us like it when we are playing and somebody spams in chat when they die because they "are lagging". Sometimes they might be, but it would be cool if you could say "Hey guys, be polite about me sucking, I actually AM lagging... Here's my ping." On the other hand for the troll that nexus dives and says "sry guis im lageing!" they wouldn't be able to say that anymore.
