HBB: You keep fighting the good fight, you cranky old language NAZI. Gotta say, I don’t use it myself, but it has lodge itself into our lexicon for better or worse. It’s not very unique in that way, either. Hopefully, the damage will stop there.
This word is a running joke in my house. We once heard Phil Donahue going off about it, so now we use when we are trying to be funny.
That and agreeance. I’m in agreeance with you! Something a girl I worked with used to say all the time.
Holy shit, Jazzercize excaped the eighties?!
I don’t really mind ‘irrigardless’ (though I don’t use that myself), but it seems that everyone is pronouncing especially (with a soft ‘s’) as expecially these days (with a hard ‘x’). Why is that? I never noticed a lot of people doing this before, but in the last few years it seems that everyone pronounces it that way now, and I actually get odd looks when I pronounce it what I presume is the correct way. 
(Another, perhaps related word is ask, pronounced like axe)

I blame espresso.
misuse of written language in general grates on me. And unfortunately there’s a lot of it “Irregardless” isn’t even on that list, and neither are many others, such as people writing about the breaks on their cars (“breaks” referring to the system of components used for deceleration).
The example highlighted (or not highlighted, as it were) by D_Odds is like fingernails on a chalkboard.
Well, I could care less…
I blame it on expresso.
No fewer. 
Doesn’t “irrigardless” have something to do with watering crops?
nevermind
Mmm, expresso. It’s the penultimate coffee!
I must be one of the few people who have never (or very rarely) heard this in person. Maybe my friends know that words have meaning? I’ve also only heard one or two people ever use “literally” incorrectly.
Well, Gaudere gives me a mulligan for that one.
And I’m sure you all know what common English word is always spelled incorrectly.
“incorrectly”
NM, Biffy beat me to it.
I had a boss that constantly used honesty/honestly interchangeably.
In all honestly.
I wanted to kill her. Honesty I did.
I have a friend who constantly says pass instead of past.
I want to kill people who use “that” instead of “who”.
What’s his heighth? Maybe you should reach acrossed and smack him.
Somehow, I don’t think many who would say ‘irregardless’ would ever have heard of the word ‘irrespective’.
My job is connected to the public school system. I just this minute received a fax concerning a literacy program that had the word “literacy” misspelled.
