Pwee comes from the word "Own", as used by gamers. Then they turned the word own into
pown, a word that is a step up form own. To top everything the word
pwee came about. This can also be used in the past tense,
pweed. It was frowned upon for a while because it was misread as 'pee-wee', but after excess use it became a word that is used almost as much as pown. So if someone said they pweed you, then that means they beat you so bad they had to resort to the ultimate gamers version of owned,
Pweed!!
