i dislike people "LOLing IRL" too. but it's nothing new. AWOL, ASAP, FUBAR, and so on. or if you grew where i did saying "kay see moe/kay see kay" was very normal.
there too many of these things to ever know/remember them all. so i wouldn't worry about it. the only ones i really can't stand are numbers or single letters. like "R U 4 this 2!?"
but a few i remember that seem to have lost popularity are:
- lamer/llama - noob and smacktard seem to be the more current.
- BBQ, BBS - be back soon, be back quick. BBL and BRB won, probably because they aren't confused with barbecues and bulletin board systems.
- roxor ....is dead but haxor lives on?
- WTH - WTF seems to have eaten him and absorbed his power...
another older one i like but never seemed to catch on hugely was RTFM - read the f'ing manual
i've been using AFK since the hl/cs/tfc days. but there was dead period of people not knowing what it meant(and me explaining it everytime i used it) but seems to be back now at least in these circles.
IRL -in real life, IDK - i don't know
i personally don't think internet slag will have a huge footprint, at least here. most of the popular ones are just shorthand for things people already say in real life. in other languages it will probably have a bigger impact, imo.
since we're getting into regional dialects... growing up in the west missouri boonies there were a lot of regionalisms(much less so in the city). most of the nonstandard ones seemed to be the "hill speak" (ozark). it's kinda weird growing up there. most people have the generic midwest accent. but some people born and raised there randomly developed ozark, southern, or northern accents. here a few i remember.
- d'rectly -> immediately, soon "i'll be there directly"
- plum' -> plain, just "that dude with the bomb strapped to his chest is plumb f'ed!"
- gander -> look
- crawdad -> cray fish
- locus' -> cicada
- sum'b**ch -> son of a....
- deer -> deer, or a tractor
- tractor -> a tractor, or a lawn mower
- pop -> soda (pop) "wanna coke?" "naw, i don't drink pop." people from even further south say "coke" for everthing which adds to the confusion. ( btw this gives one endless ridicule here on the west coast....)
- you all(y'all) -> personally i think "you all" was more common
- mighty -> very not really used nowadays but sometimes you'd hear it
- hanker -> want sacastically="you hankerin' for an ass kickin'?"
- reckon -> guess, "bet" like "sure, i bet.." - > "shore, ah reckon."
- yonder -> "far over there" here(close), there(away), yonder(far) "way over yonder"
- dude -> "city slicker" (not surfer talk originally...) (see "dude ranch")
- overuse of "the" -> "he went to wally-world" "he went to the wally-world" "i love the video games!"
- -n -> eg theirn, yourn, ourn, etc (not that common nowadays, hardcore ozark. but i'd hear it here and there when i was down there)
- "them" is used instesd of "they/those" sometimes
- i've noticed people out here say things like "highway 15" but back there it was always "75 highway"
- no one in "misery" calls the state "mizzou(la)." new englanders do. sometimes "missoura" though
- we're more likely to say "muddy moe" than "mighty moe"
- and never... never... NEVER call something that is grilled, "BBQ!"
i use some(not all though) of these myself from time to time in the real world. though, i have the world famous "omaha accent." which you think is "no accent." but after moving out of the area southerners think i have a mild northern accent and northerners think i have a mild southern accent. and sccording to the germans on TS my american accent is really thick(which was news to me).
i've also heard more than once that regionalisms and accents are actually getting stronger, not weaker. people are peobably a bit more self aware these days of such things.
