Managerial Reach-Around

This is when a startup manager/CEO/founder sits over your shoulder, watching you code/design and providing unhelpful input. In the most extreme cases, they are physically touching your keyboard, mouse, and/or screen.

I've been trying to get work done all day, but the CEO is such a shitty manager that he keeps giving me a managerial reach-around. Why can't someone teach him to delegate?!
