cotton mouth 

Cotton mouth is not only a very dry mouth from smoking pot, but involves having small bits of mucus and spit, lining mainly the roof of your mouth feeling like cotton when you rub your tounge against it.

Fish-mouth Syndrome 

A prevalent facial defect found on SJWs and feminists where their mouths are permanently slunk down to the sides of their chin, thus giving the appearance of a retarded fish. These features are often accompanied with the standard privilege checker glasses, a huge honking nose that blows when triggered, and unfitting hair colors.

Doctor: I'm sorry to say that you have developed Fish-mouth Syndrome due to prolonged exposure to Tumblr.

Girl: PATRIARCHY!!!!!!!!!!!!!!!
