I've always had a thing for Mercedes Benz and last year I picked up a SLK at about the same time as I was trying to think of a Twitter handle... hence mercbezerk.
Started using whirrx after upgrading the turbo in my STi. So many people commented that they loved the whirring sound it made, and if you try pronounce WRX, it might sound like Whirrx. Got that as a license plate and used it as a handle ever since.
I'm pretty sure most people have heard the phrase "Vegas baby, Vegas!!!", well my username is basically that. 702 = Las Vegas area code and just added the baby at the end, so basically my user name is "Vegas baby" but in a more subtle way :big_boss:
