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
