Facepalmist 

A facepalmist is someone, who by virtue one's idiocy (unaccountable by a disease or disorder), gives the reader/listener an inevitable, painful collision between one's palm and the face, one of the reasons being the utter disgust of having to share the identity of "human" with the facepalmist.

This person is not the regular ignorant person (which is basically each one of us) who says something stupid once in a while. Both the quantity and quality of stupid matters, he/she has to be very stupid and often stupid. The suffix "ist" is justified by the expert level stupidity in a facepalmist.

Facepalmist: If some stars are 100 light years away, then how do I see them? I am not 10 million years old, stupid cosmologists!
Anyone with basic common sense: *Facepalm*

facepalmfamous 

A term coined by YouTube user gineriella to describe those that have become famous because of how awful and facepalm-triggering they are. Mostly used to describe viral stars like Rebecca Black.

Person 1: Did you see that the 'Hot Problems' video has gone viral? Those girls are basically famous now.
Person 2: They're not famous, they're facepalmfamous.

faceplam 

When you attempt to facepalm yourself in an intensely sarcastic fashion, but miss your face.

Pam, did you see that? Lana tried to facepalm herself, but missed.

*falsetto* FACEPLAM.

Seriously, how can you miss your own face, with hands as huge as that.

Facepalmtastic 

1. When the best, or only, appropriate response to a situation is a facepalm from a third party, because words just cannot describe the full extent of thoughtlessness or idiocy as is evident.

2. When you see firsthand, or hear about, somebody doing something so stupid that you cannot imagine said person NOT facepalming themselves, so you facepalm out of pure sympathy.

This textbook is facepalmtastic because the publisher let the author get away with saying this:

"Cultural Studies insists that culture must be studied..."

EXCERPT FROM:
Dines, Gail and Humez, Jean M. "Gender, Race and Class in Media" 2 ed. page 10.
