Yoink!- when I pick something up
Neef!- general exclamation
WAGGGH!- means everything
Yofi. It’s Hebrew, it means something like “nice”. It can mean anything depending on the tone of voice.
Also, “bread,” but this is with just one friend. We decided that since the phrase goes “the best thing since sliced bread” that bread must be truly awesome, and if something is very cool, it is bread.
Fuck.
Sums up just about everything.
My husband and I have an all purpose phrase: “But why, Greg?” And it’s spoken in a (hard to describe) nasally, high-pitched, Muppetish voice. (It’s kind of hard on the vocal cords.)
We got it from a Greg Proops stand up routine. This was his imitation of the unwashed masses whenever he spoke some great truth or said something utterly profound that supposedly the common man doesn’t get.
Greg: Blah blah blah
Unwashed masses (voiced by Greg): But why, Greg?
Greg: Blah blah, you get the picture.
So when one of us says something equally profound, or just confusing, goofy, or dumb, the other interjects, “But why, Greg? Why?” It’s also a good outburst on long, boring car drives, or just whenever it’s too quiet. I have to fight the temptation to use it at work; they wouldn’t understand.
Not really a word, but I am fond of the versatility of a good piraty “Arghhhh”
My APW is mair- something like that anyway, the meaning is defined by the tone. It’s just like that. I have no clue where I got it from, maybe it’s that inquisitive cat sound or something.
Bastard… but said with the heavy boston accent its more of a bahstid. when i left the area and lost the accent i stopeed using it, but now that i’m back i use it alot more. It just sounds better that way…
Gr8Kat - we have one just like that too. "But what about BOB. You have to say the “Bob” with jsut the right tone - and I can’t explain it.
I have 3 actually.
Great.
Terrific.
Wonderful.
All can be used as a generic comment to express sarcasm, displeasure, neutrality, excitability, or support.
Fucking A!
Actually, it’s not totally all purpose: it’s mainly for positive situations.
What’s the dealio? is my confusion/anger/negative phrase.
APW? Kinda. Moo tends to work. Also, some SDMB sig mentioned “Mu” in the chinese sense about how to answer the question “Does a dog possess Buddha nature?” (or something of the sort). That works too.
Also, if I want to spice up the conversation with a friend, I will add the letter “B” to the end of a few words.
“So, how was the baseballb game?”
“It wasb pretty fun.”
“Whob won?”
“Atlantab.”
So words just kinda appear.
“whaaatthaaafuuuhh–”
man, constantly…
Indubitably
Nifty. Can be said with either sarcasm or wonder.
I usually just go “Pshhh…”
And I also go “ohkay” like that Antonia(sp.) on MadTV
Online,
yeeeeeeeee, yeah, sweet and sweetie
and off line, well that’s Swedish words.
I usually use “dealie” or “thingy” - 'cuz I can’t ever get my words to come out of my mouth when I want them to. I also use 14 million for every exaggerated large number. Almnost every time! “I’ve told you 14 million times that the dealie goes on top of the thingy!”
All these replies, and not one mention of OY?
Leo Rosten: OY is not a word; OY is a vocabulary.
79. I guess that’s more of an all-purpose number, kind of how the writers of the Bible use “40” to mean “a lot” 
It’s usually coupled with “jillion” for the perfect over-blown exaggeration effect.
Meow is another one of my favorite all-purpose expressions. It, too, is a vocabulay.
Helvete!
It’s best to draw it out…
