brainface 

A whimsical word used to describe someone who typically says something that alienates one or more of his/her friends on a daily basis, shouts random nonsensical words at awkward moments, tells stories that go nowhere and should probably stop one to two sentences before they actually do, makes references to world of warcraft knowing full well that no one in his/her social circle plays the game, and is frequently prone to bouts of dementia in which "every girl on earth is horny for them".

Variations include, but are not limited to:

Facebrain, Brainhead, Headbrain, etc.

Taco bell drive-thru guy: "How are you tonight?"

James: "This is a nacho cheese order! HAHAHAHAHAHA!"

Dan: "Oh...my...god. What a brainface."

brainfreeze

N. Ipsilateral, temporal, orbital and or bilateral pain resulting from rapid cooling of the spheno-palantine ganglion (roof of mouth), often a result of ice-cream or slurpees, although any cold substance can trigger such a response. The pain is a result of dialated blood vessels in the brain brought on by spasms of the nerve endings and typically peaks in about 20 seconds from the point of ingestion.

After rapidly ingesting the Slurpee, Bob winced in pain as if he were having a migraine.
