ur ancestors incestors

This is the by far WORST insult that can ever be used. Nothing will ever be able to top this insult, as soon as it is said life as we know it will cease to exist.

Johnny- "ur mom gay"
Fred-"ur dad lesbian"
Johnny-"ur sister a mister"
Fred"ur bro homo"
Johnny-"ur granny tranny"
Fred-"That;s it, ur ancestors incestors"

The universe implodes as everything that exist is destroyed. All you can hear is the screams of every single person being tortured in hell as everything comes to an end with one final explosion.
