McBeastin

1. Last name given to someone who is completely epic.
2. This title can be self proclaimed or given by a friend or friends. Unless one has experienced a McBeastin, one may not name a McBeastin.

Megan Mcbeastin is the coolest person around!

McBeauty 

When a certain young lady presents outstanding natural beauty, she may be termed a "McBeauty".
Has some relavence to the chat up line "If you were a McDonalds you'd be a McBeauty!" ;) Often followed by a whole lot of ignoredness...

"check that McBeauty out! Sheesh!" (elevated heart rate experienced).

Beaty McBeaty 

To describe someone/thing who looks beat af - a real eyesore.

A play on words with the word “beat” and utilizing “Mc” from McDonald’s for extra emphasis on the level of extreme beatness.

Boy: Damn girl you looking Beaty McBeaty this morning!

Girl: Leave me alone I’m not wearing makeup asshole
