I sure I am not the first person to wonder this. So I might as well be the first person to ask this. Sometimes on a thread on these boards someone will jokingly(-?) insert the word “Whoosh!”. This obviously means something. But what? Also, like the hampster thing, it might be a reference that only the people on these boards understands.
Someone please help me out here in understanding this odd reference 
.
“Whoosh” (with or without the exclamation point) is a way of alerting a poster that they have misunderstood something in a previous post- taking a joke as a serious comment, for instance.
The ideas is that the comment flew over your head, hence, the “whoosh” noise.
Something that’s been around a while, asked about (around here) a lot, and is everywhere.
This goes back to the idea that these boards are powered by hamsters running on their little wheels. When the boards are particularly slow or stubborn, you will often hear talk of the “hamsters being underfed” or some such.
And don’t forget the derivatives, like the verb “to whoosh” or noun “a whoosh”:
“Are you whooshing me?” (Are you kidding me)
“You’ve just been whooshed!” (You just fell for something as gospel when I was really putting you on)
“Is this a whoosh?” (Is this less than factual or serious, more of a joke)
Let’s hope the hamsters never get whooshed.
Why the misspelling of hamster, though? Is it deliberate, like the use of “merkin” for American?
I had a friend in college who, when told that something had whooshed over his head, would often reply “Yeah, but I caught the splash off the wall!” 
hampster is the offical misspelling of hambster.
All right! So our Board’s engine is German-made!
So this is like a meta-woosh?
Nah. It’s just that the wheels that they turn by running are made from old, discarded laundry baskets and we’ve conflated the spelling of the hamsters running in hampers.
This was a significant upgrade from the old, rustic, discarded orchard-style bushels with pokey, pronggy, snaggy wire bits sticking out. They will not be missed.
Formally that’s it, but as always it’s the functionality (how the word is meant or intended) that is more interesting.
Thus, someone who comes up with a different take on a contestable sdmb issue that has largely lost its contestable nature, and has become part of the taken-for-granted “commonsense” background knowledge that is now assumed, will be whooshed when the whoosher knows perfectly well that the whooshee DID get the point, usually an assertion of some kind, but was contesting it. It’s a surprisingly effective put-down, given its crude, manipulative nature.
So, when you see this post responded to by a poster going “Whoosh”, you can be pretty certain that it must have hit near the mark.
Some people raise their voice when they know their arguments are weak. Others lose their temper. Still others go “whoosh”.
And I won’t even mention those who quote those dreadful old bores from Monty Python’s Flying Circus…
Just like Volkswagens. That’s why they feed the hamsters all that farfegnugen.
Since the question has been answered, I’ll just pop into say that my ex-g/f used to call it a ‘trapeze act’ – which is also over one’s head. She’d also make a palm-down slashing motion over her head to indicate a ‘trapeze act’.
Don’t pay any attention to the above answers. The fact is that none of them has any idea what “whoosh” refers to and are conspiring to pull your leg about the meaning of the word.
Whoosh is a referance to this site and it is as simple as that. 
If you bought that one, you have just been whooshed.
The reason we use hampsters instead of hamsters for our wheel-beasts is actually much simpler. You see, due to the strenuous physical and ærobic demands of powering this board, we use only hampsters with prior dance experience. And as everyone knows, it’s hampsters which dance, not hamsters.
roger thornhill, I’ve never in my time on this board seen “whoosh” used in that way. Or was that supposed to be some sort of bizarre meta-joke, deliberately missing the point of whoosh?
It’s completely nonsensical. It’s just that roger can’t bear to miss a chance to whine that people disagree with him because we’re caught up in our prior prejudices and he gets no respect because he’s (sorta vaguely) new here. Apparently the thought that we just disagree, or that some of his ideas are wrong, is something that he can’t bear to imagine.
Wait a minute, this is not the forum to get out the beating stick for people you disagree with.
If you have a problem with someone, take it to the Pit, don’t do it here.
