Starting an argument with a counter then saying "ur mom" is the most pathetic comeback ever

Alright guys this is a big one. One that a lot of us has seen many times. If you start an argument with a counter and then the guy says "ur mom" in return then just take the counter, mute the guy and leave. This isn't a tip towards the instigator, it's one towards your average Joe who always needs the last word or else pulls his hair out and cries about it, and this is a lesson for you, you aren't going to get a witty comeback off of this guy, accept it and leave. Your pride is costing you a counter.
