Started on Xbox Live on Gears of War by me.
'Shlag' is a word that can't offend anyone (Unless their stupid enough to think you said slag)
Shlag is a 'joke' sort of word.
It was a online word, but I used it in school and now people use it all the time.
"You threw my book you cheeky monkey"
"You threw my book you shlag"

"You a shlag"
"No, you a shlag"

"You boomered me!"
"Sorry shlag"
