Plumb as in "Plumb a door frame or cabinet?" Plumb is having something 90 degrees to level. The floor is level and the door frame, the vertical, up and down part is plumb in relationship to that. I'm sure this term comes from using a Plumb Bob. That's a heavy pointed ball on a string.. It will always show you the plumb line.

The term "half a bubble off plumb" originates from the use of a spirit level, a tool used in construction and carpentry to measure vertical alignment. When the bubble in the level is centered, the surface is perfectly vertical or "plumb." If the bubble is half a distance away from the center, it indicates that the surface is slightly off vertical, hence the phrase is used metaphorically to describe someone who is a bit eccentric or not quite right in their thinking.
