So me, my grandfather, and my brother's ex-wife were all in Las Vegas...
I was planning to visit my Grandparents in Texas before my family and I were going to move there from California, and they just so happened to be taking a small vacation to Vegas. So we arranged that me, my brother, and his wife at the time would meet up with my grandparents and leave me with them and then I would return to Texas with them. We would spend a week having fun in Vegas together while staying at the MGM Grand Hotel before we left.
One morning, or rather afternoon as I had slept in on the amazingly comfy bed in the hotel room, my grandpa walked in from just having lunch at the buffet on the ground floor and noticed my bedhead, I had really long hair at the time, and said, "Your hair looks kinda kinky." Not half a second later, my brothers wife walked in behind him and said, "mornin bobo!" Which she often called me. My grandpa looked at me, then back at her, and then once again at me and slowly sounded out the name, "Kink-ky-Bo-bo", and then we all laughed. The name was funny and had a weird catchiness to it so I started using it. Its now the name for my entire gaming identity. Everything from my Xbox Live Gamertag to my Battle.net account is Kinkybobo. If you google it, 80% of the results are my profiles. League of legends account, bungie.net profile, world of warcraft characters... All me =P
