The insult "Ur mom gay", but with a huge upgrade. This insult has enough destructive power to end all reality with a single use. Even God himself cannot withstand this insult. One use and God will be vanished forever.
Bob: Ur mom gay
Phil: Ur dad lesbian
Bob: Ur granny tranny
Phil: Ur grandpap a trap
Bob: Ur sister a mister
Phil: Ur brother a mother
*Nothing happens*
Phil: What?! How are you still alive?!

Bob: Witness my power fool.
Bob: UR MOM DUMB

*Reality shatters and the universe collapses. God is banished*.
