Ur mom

1. A woman who most likely gave birth to you and raised you. Probably also your dad's wife.

2. An extremely stupid "insult" used by people who can't think of an at least decent comeback to pretty much anything. Usually followed by a random dude who comes out of nowhere and shouts: "OHHHHHH".

1. Kid: Dad, how was I born?
Dad: You see, your mom carried you in her stomach for nine months and then the doctor helped you get out of there.
Kid: Ok, but how did I end up in my mom's body?
Dad: Uhhhhhh... I'll tell you when you're older, ok?

2. Person1: Wow, you're really stupid.
Person2: Ur mom is stupid
Random dude out of nowhere: OhHHhHhhHHhhHhHhHHhhh! GeT rOaStEddddddddddd!!!!!!!!
Person1: Wtf

ur mom

Something that can be said as an answer to everything, it can also replace a noun in a sentence. You can also turn around a few words from the last sentence said and add ''ur mom'' somewhere.

Note how when used, it will cause the person you're talking with to automaticaly have sexual thoughts about his mother.

Random: yeah it's a bit tight
You: ur mom is tight

Random: i'm eating buffalo wings, it's dirty as I type but I really like wings
You: ur mom like it dirty

Random: brb bathroom
Random (several minutes later): back, was a bit long, was out of wiping paper lmao
You: me too but ur mom wiped me
