SDUPO 

(stoo-poe)
Symptoms Disappear Under Professional Observation

Common frustrating occurrence of having all symptoms of an intermittent technical problem completely disappear when one takes the vehicle/computer/child into the professional responsible for diagnosing and fixing the problem.

Tech Support: "How can I help you today?"
Victim: "My volume doesnt work."
Tech Support: "Ok. Boot up for me?"
Windows: "Ba da ba Bing"
Victim: "I guess its a SDUPO for now."
Tech Support: "It appears you've wasted your entire lunch-hour, and will waste another tomorrow when the problem returns.
Victim: "Yes. Yes I will."
