The ultimate form of an insult. Usually used as a finishing move on the strongest of opponents to show that your intellect is stronger and more advanced.
Person 1: You so lame that not even gravity will pull you closer
You: ur mum gay lol

Get the ur mum gay lol mug.
This is the almighty insult you should NEVER use upon an oponent unless absolutely necessary. The last time this insult wad used, it was used by Alexander Graham Bell in a prank call. As a result of this, the fabric of space itself was torn into shreds, resulting in evolution reversing into what we are today. Using this defense mechanism will end the opponents career and send he/she into a deep depression. Dont expect to live to see the next day as an antidote recently discovered by acting legend, Bill Nye The Science Guy. The phrase "no u" resulted in the defender dying because blood stopped flowing into his brain from chocking literally on Bill's entire ass cheek.

Use with caution
*points at teacher "Ur mum gey lol"
*teacher rips off clothes and sets into his battle stance. He slowly develops a raging blue ball of ki in between his two hands and screams "NO U" as he releases his deadly blast. The entire school is devoured by a quantum flux*

Something that someone in the presents of a bunch of memers will sub-consciously type into their search bar while thinking of something else while their parents are in the room.

You may laugh when you hear this, cry because your mother divorced your father because she's gay or angry because you hear this from the zoomers on the bus.
mum and dad: *mumble* *mumble*
me: I wonder what they are saying...
the search bar: ur mum gae lol
