Ur Mom

An annoying, yet addictive slang for when someone has nothing else to say.

Whoever: "What's your favorite color?"
You: "Ur mom."

Ur mom

Ur mom is a word used by road-men and chavs in 2021 and further on, the people who used these 2 words think they are funny. If you are reading this in another year then 2021 and you hear someone say “ur mom” slap them across the face and make them cry, these people think they are hard and are fake bullies in your secondary school. Call them shanks and tell them that there mums will die one day.

“Heys whats your favourite colour?”
“Ur mom”

Ur brother a mother

An insult typically used by 17 to 19 tryhards. Usually when they are losing. This is also one of the worst insults ever and whoever you tell this to will have something bad happen to them.
