Ur Mom 

Ur Mom (Yoor' Mäm) n.
A way to let your home dogs know that you are sexually attracted to their birth mother leaving them with confusion on what you actually meant by this. Any bystanders will then outrageously yell ohhhhhhh leaving them with more confusion than the conversation started with.

Home Dog: What you doing over there
You: Ur Mom
Bystanders: Ohhhhhhhhh!
Home Dog: 😕
