Call me old-fashioned,
- but I still like 'woot!'. As an expression of joy, it pretty much encapsulates 'whooping with joy' into a word in an almost onomatopoeic manner.
I also like 'Wiigii!'.
Recently, in the Dungeon's & Dragons Tiny Adventure application on Facebook, the following terms were born:
Mars'd (or marsed) - Indicates a string of bad luck, particularly in the realm of gaming and technology. Servers down? They've been Mars'd. Rolled a 1 nine times in a row in Iron Man? Totally Mars'd.
Jindra'd (jindraed) - The opposite of Mars'd.
And, the crème de la crème: Wibble!
If anyone can define 'wibble' for me, go ahead.
