OTSTOP error 

Common shorthand in phone tech support circles when a caller's device won't work due to not being plugged in, turned on, or installed yet. OTSTOP stands for "Obviously Too Stupid To Operate Product."

"Customer hid SmartPhone by submerging in fish tank to surprise her son, causing OTSTOP error on startup."
