Tall, solitary weirdo who spends a lot of time building stuff or making a computer do a thing or making a car roll forward and backwards and sideways and generally killing time en route to our exit off this mortal coil. Maybe you want to use the term 'nerd'. Sure. Perhaps 'boring idiot'. That's rude, but okay.
Grew up all over the south and raised in the deepest forests before packing up and living in NYC for a little bit longer than is healthy for any person.
