If anyone else had called me this I probably would have been a bit annoyed but there is a story behind the nickname that I was inadvertently given once:
I used to live in Cameroun and while there I became quite friendly with a number of Christian missionaries. One particular family of missionaries had just arrived from Tennessee, a man, his wife, and his three young children, aged 2, 4 and 8. They were gearing up to travel with the nomadic herdsmen in northern Sudan, and the local missionary community decided to throw them a "good luck and Godspeed" party which I was invited to. As soon as I showed up, the littlest child just stared up at me and his eyes turned round. He pointed at me and said, with that southern twang, "Mr. Tree! Mr. Tree! Mr. Tree!"
It sounds like everyone has a great many of the same names given to them at somepoint and I like the comment of how some peopel "think" they are being so original but have no idea how wrong they are! I am 6' 8" I get jolly green, sasquach, big foot, ( even though I think I have small feet (13) reletive to my size) stilts, lurch, conan, sometimes just a casual "hello Tree" tall one, I have never been called giraffe. my most favorite nic name was givent to me by my Uncle, he calls me Diesel cause he figures I am big enough to burn it! and its cool cause I own a diesel truck! very comfy to ride in for tall people
"Lurch"...(from the Adams Family)..
"Mon Gros Tabernacle"..."my big church" in french..
Skybox, Moose, Lurch, Crazy Legs (I actually like that one)
