ur ancestors incestors 

"ur ancestors incestors" is a forgotten insult burried deep in time. It was first used in the 1900s when a young lad was searching for a comeback from the dreaded "ur granny tranny". This insult is so dangerous that the government had to hide this insult. It breaks through the fabric of time and space itself, but as F.B.I. agents were shocked at Donald J. Trump's loli porn collection they were careless and had accidentally exposed the insult in the form of a meme.

Josh: Jay, ur granny tranny.
Jay: Pathetic. ur ancestors incestors
*Jay made Josh cease to exist, the fabric of reality broke down, even if only for a moment.*

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"

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.
