sick (up) definition
sick and tired
Also, sick or tired to death. Thoroughly weary or bored, as in I'm sick and tired of these begging phone calls, or She was sick to death of that endless recorded music. These hyperbolic expressions of exasperation imply one is weary to the point of illness or death. The first dates from the late 1700s, the first variant from the late 1800s, and the second variant from the first half of the 1700s.
