Paul Gillin, a very smart tech editor/journalist (PC Week, Computerworld, TechTarget) and consultant once coined a phrase for the type of person who enters the express checkout lane at the grocery story with more than the maximum number of items:
Expresshole
I need a word for the emotion you feel in a convenience store when the person ahead of you plays his or her paycheck on scratch tickets and lottery numbers, dooming you to five minutes of: “And I’ll take three Quick Pick Megabucks of Welfare and seven Scratch Slots and eight ….” This word is dying to be born.
And, I need a word for the guilt one feels on an filled-to-the-brim airplane, when someone else breaks wind, makes a stinky, and you worry that others think you did it. I think the psychographic profile generally lays suspicion on a) men, b) big men, c) big men who are sleeping.
For the person driving down the road with his/her blinker on not intending to turn — “blinking idiot”
This reminds me of the Rich Hall “Sniglet” schtick from HBO’s Not Necessarily the News.

One of my favorites:
Brattled (brat’ uld) – adj. The unsettling feeling, at a stoplight, that the busload of kids that just pulled up beside you is making fun of you.
