Anus mouth 

When someone talks a lot of B.S. and you know every word they say is full of sh*t

Nick: Did he really meet the President for dinner?
Curtis: No, he just has a big anus mouth.

Anus Mouthus 

A pseudo-Latin expression. It's an alternate way to refer to the young girls (and sadly now more and more boys as well) all over the internet who are going the duck face on the Facebook or MySpace pics.

-Have you seen Jenna's new Facebook pic?
-Yeh, she totally looks like an Anus Mouthus...
