In Japan, it's almost like "lol" or "haha". It comes from the term "笑う", or "warau", and it means "to laugh". The more w's, the more ha's, so to speak.
"That's weird haha"

"What the hell are ya doin', lol"

"Did you see that!? Hahaha!"

A Work Wank.

When it all gets too stressful at work, one takes matters in to their own hands and provides a little relief.

Wrong window.
When you have multiple chatrooms/chatwindows open, and by accident, you enter your text in the wrong window.
