When someone eats with reckless regard usually involving and not limited to ignoring errant food particles on face and, if applicable, in facial hair, shoveling food into one's mouth before completely swallowing the previous bite, utilizing every finger on every hand, and uncontrollable stares from spectators. Throwing up results in an automatic disqualification.

Refers to the (unfortunately very-seldom-practiced!) consideration of using a separate hand-held rubber eraser --- or at least to slip on one of those much-longer-lasting wedge-shaped "supplementary" eraser-caps if you know you'll be doing a lot or error-expunging --- to clean most of your mistakes instead of just mindlessly consuming your pencil's minuscule built-in eraser, so that you don't wear da entire 0%!$&#@ eraser clear down to the metal ferrule before the pencil's even been "sharpened away" much at all, causing any unfortunate person who subsequently attempts to use said pencil to not have any eraser left for "emergency" erasures (i.e., where he needs to make a quick correction in a tense/flurried situation, like trying to hastily jot down a phone number or address, or to quickly fill out a form where neatness is a must). It helps eliminate waste, as well --- think how many still-perfectly-usable pencils (i.e., they still have most of their "length" remaining) likely get discarded just because their erasers are worn down.
I always bring along a few pencil cap erasers in my purse, since I know how few people actually practice pencil-eraser etiquette, and so oftentimes the only pencils that will be lying around for people to use will not have any eraser left.

P.S. There's also such a thing as "pencil-POINT etiquette --- if ya wear down the lead in a "public" pencil, such as a string-tethered one for a "customer comments" notes-box, practice a little fellow-human consideration by scraping away a bit of the wood at the tip to expose a little of the graphite core again (here's where always carrying a small pen-knife --- or even better, one of those tiny two-finger-grip "dog-bone" or "hourglass" style sharpeners --- can come in handy), so that da next patron who wishes to fill out a store-satisfaction card can have enough of a point on da pencil to actually do so!

A few simple "no brainer" rules that, if we'd all follow them, would make posting/reading paper ads/notices a much more pleasant and peaceable experience for everyone involved.
The "perfect five" rules of community bulletin-board etiquette:
(1) Each poster should be limited to one message per board, unless he is posting two or more "unrelated" ads/notices.
(2) Notices should be a maximum size of an 8-1/2X11 sheet of paper --- don't selfishly hog a whole gigantic portion of board-space with those 0%!$&@# huge-a** blaze-orange/fuchsia/chartreuse banner-sheets from da Dollar Tree's art-paper bin!
(3) Only attach notices to a blank portion of the board --- don't imperiously plaster your poster over everyone else's, regardless of whether you think your message is so much more all-fired important! If there’s insufficient room, make at least a half-a** effort to solve the problem rationally/fairly --- shift other people's sheets around on the board to form a "tighter" grouping, seek out and remove any "obsolete" (event-dates that have already passed) messages, etc.
(4) Don’t use the last “empty” thumbtack/pushpin on the board, or snitch one from someone else’s page! If the supply of available fasteners is running low, add a few tacks/pins of your own! Plus if you see someone else’s poster dangling/flapping by just one corner, pin it back up again.
(5) Choose a spot on the board that’s appropriate to your ad’s subject/urgency. If it’s about a lost/found valuable, super-important event, or desperately-needed item, place the ad near the center of the board. But if it’s merely a “for sale” ad or general notice, place it near the board's top/bottom/sides.
