Since the inception of texting and IM'g, WTF has been a universal acronym that gets regularly used in chats, between cell phones and computers. Because it easily rolls off the tongue, or computer keys a tad too quickly, I find myself dropping the WTF bomb a tad too much — yes dad, you're right, it does "cheapen" me. Nonetheless, when you can't find the strength from within to conger up the confidence to say WTF to someone's face, I suggest investing in one of these WTF stamps. . . which will surely save you embarrassing face-time with your co-worker.
Unfortunately I don't know where you can buy one (my Spanish is pretty rusty), or how much they cost, but at least we know they do exist, so we're halfway there. Thanks for adding this to our geek gear list TeamSugar user eruntale!
