Woot is the word
Back in 2005 Podcast hit the dictionaries, but two years later we are truly entering the digital age as Meriam-Webster will be adding the word W00T (I prefer the double zero instead of the o’s). The word is defined as:
w00t (interjection)
expressing joy (it could be after a triumph, or for no reason at all); similar in use to the word “yay”
I think you could call w00t a social expletive, though I say that only to ask if we have any spatial expletives. I just can’t think of any.
