"Slash-Slash, Whack-Whack" OR "What a Whack Job!" OR "You Learn Something New Every Day" OR "Add this to the Microsoft Lexicon!"

An e-mail exchange between me and my boss after a meeting with a client at Microsoft:

Me: What is “WAC (K? CK?)-WAC” that J referred to today when he spoke of users accessing info?

My boss: "He probably was referring to ‘whack’ which is just the word for the ‘back slash’ symbol - \\"

It's Friday and I must be really tired because I found this giggle-worthy.
