How do you pronounce wOOt and teh ?
I say w00t all the time.
I’ll even say owned! but not pwned.
A few other l33t speak words have filtered down into my verbal vernacular, but not many.
I say woot. And when I say it, it does rhyme with boot.
I don’t say it often though.
I say woot, too, in times of great victory, like when I make it through the intersection before the light turns red.
Yikes!
“teh” rhymes with “the” but has no “th” soft sound, just the hard “t” sound
I say “woot” sometimes, often in jest, sometimes in sarcasm.
I’ve been known, when playing an MMORPG with my husband and I execute a task even the tiniest bit better than him, to gaze, deadpan, at him over my laptop and say, “pwned.” (sounds like “poned”.)
If I screw up or die, I will sometimes say, also deadpan, “I am teh suxx0rs.”
(sounds like “I am teh sucksors.”)
I wouldn’t say them in public, and I never use them seriously. I try to use them only at a time when I’m sure I could at least get a giggle.
It is teh tough crowd I can’t pwn when I r0xx0rs in my b0xx0rs.
Woot.
OK, I think I’m ready to take a stab at this one (without cheating and Googling): multimedia online role-playing game?
(please check one:
(___) w00t!
(___) teh suxx0rz)
Check. 
But you are pretty close. Massively Multiplayer Online Role Playing Game. My poison is Everquest II.
It amuses me that some people (mostly youngish ones) say “LOL!” as an exclamation. Rather than actually laughing out loud, they use Internet chatspeak that refers to laughter. I am tempted to respond by saying “WTF?”
Didn’t that word come from Tag Team’s Whoomp! (There it Is) or 95 South’s Whoot! There it Is? That’s how I say it.
I will say “w00t” in casual conversation. It rhymes with “boot”.
I’ll also say “That r0xx0red my s0xx0rs/b0xx0rs” and “that’s completely fuxx0rs/ed”.
If someone’s in trouble/shown up by someone else, I’ll say that they’ve been “owned” or sometimes “owned-with-a-p”
When something really tickles my fancy, or if I’m being overly sarcastic, I’ll often come out with “It’s teh w00tz0rs”. “Teh” is said just how it looks “T” then “eh”.
I’m strange, indeed.
If you’re a resident of Shelbyville, and a Springfieldian wanders into your town you’re obliged to call, “Woot woot” and point a finger at the poor rube.
Just statin’ facts.
I have been known to say it. This has happened a total of three times. I was instructed by a horrified friend not to say it anymore. I have gone back to my standard “Woohoo!”, picked up from an ex. At least I don’t say it all the frigging time like he does, though.
Methinks I need less easily-embarrassed friends.
I’ve only just started saying w00t, always in a very deadpan tone of voice to indicate that I would certainly never say such a thing, but am making a rare exception. I am pretty old for an expression like that; the ironic detachment shows that I am aware that it is an expression for teenagers that I, an adult, am using. I’ve said woo-hoo as long as Homer has, just like he does. I started using teh years ago. I don’t know if that makes me really cool or unusually dumb.
I have just used w00t, teh and semicolon (correctly) in the same post, which i totally prawn.
You just reminded me, saoirse - I call porn ‘pr0n’ on a regular basis, too 
I use woot. Yep. And I don’t use it with any irony. I also use woohoo!
Woo on the other hand is generally sarcastic.
I’m very prone to picking up little catch phrases. Squa, teh suxx0r, pwned (pronounced poned for some reason), gmeh, jinkees, doh, basTARD, yo. I spend 95% of my time around people who are much older than I am and who are baffled by the slang of my generation, too, so throwing in some newer stuff just spices things up. Woot!
I sometimes use w00t, but that’s because I would say “woo” and the t sound just fits. It’s actually the only netspeak I use, even on the net, because what I type is what I say (barring typos). I might start using “pwned” too, because of my brother’s influence.
I say it sometimes in an ironic way. But I did it more around my college friends - that’s where I first heard “woot/w00t” and it’s not funny if you don’t already know the phrase. My old roommate and I liked to toss around leetspeek that way, it was funny. He’s the one who taught me that “pwned” is pronoucned “poned” - I thought it was said “p-wand.”
A little bit of me died the day I saw some guy bet 1337 dollars in Final Jeopardy.
I say “w00t” and “pwned”, but it’s mostly to make fun of the fact that my SO is a CS major and we’ll be graduating soon (i.e. ‘growing up’), so I’ll be slowly weaning myself off of that type of language. I think I’ll keep saying it once in a while since it’s one of those silly things you say that only other geeks and nerds will get.
