look up any word, like the eiffel tower:
wuut is simply wuu2 which we all know means "what you up to". This has been changed because now not many people type using numbers anymore :)

This technique can also be used in say wubu2-wubut and others similer
one: heya x
two: alright babe?
one: yeah taa, youu?
two: good, yeah thanks. wuut?
one: on urban dictonary. youu?
two: sames!!!

His mistake in trying to impress the girl came from using the more common w00t instead of the fashionable wUUt!
