fuckit switch
A type of trip fuse located in the back of the brain. When multiple tasks, deadline pressure, and unrealistic demands threaten the brain's delicate circuitry, the switch pops into "fuckit" or "safe" position, allowing for rest, relaxation, and a healthy attitude readjustment.
"If that phone rings one more time with another problem, it's going to blow my fuckit switch."
