Diff

To do a Diff is to power level a character on an MMORPG from the bottom to the top level available in record amount of playing time. MOST who do this, have intentions of their account going to a Ni Hao website (Ni Hao = gold farmer)

(Unregistered): hmm maybe I should do a diff with my druid so we have a tank in guild eh.

Diff

Short for "different", a negative term used to describe someone or something in a derogatory manner. Like there is "bad naked", this is definitely "bad different"!

"Why are you spazzin' out? You are being totally diff!"

"Oh my God, I cannot believe I dated him back in the day; he is completely diff."

"Yeah, I didn't really like that movie much."

"You're right, it WAS kinda diff."

"For the love of God, stop being so diff."
