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.
