smugcat
a "smugcat" is not a cat, it's an expression or attitude. When you have a new outfit on, or get a new car your a "smugcat"

Smugcat is also often used to describe the behavior of dogs when they are proud of themselves or showing off.

Smugcat originated from the smug look my parents cat would always give me from the top of her kitty condo.
