pinstriper
One who performs pinstriping, which is the application of very thin lines of paint used primarily to customize the decoration of motorcycles and automobiles. He's one of the biggest pinstripers in the hot rod community in America. It wasn't until I was nearly 50 that I found my calling as a pinstriper for motorcycles.
striper
military slang An officer with one or more stripes on the sleeve of their uniform to indicate their rank or length of service. Typically used in combinations specifying how many stripes are on their uniform. I knew the mission was a bad idea, but I was just a one-striper, so I kept it to myself. She was the only three-striper selected for the Brigade Staff. Everyone else was either a four-striper or a five-striper.
