Not to be confused with a "Test Call" (which in telephony, is a telephone call made to diagnose a problem or prove/disprove a fault), a "Testy Call" is a call made begrudgingly to placate someone else speaking bollocks when they claim a line isn't working.
"Guys, the customer is claiming their lines are not working again, can you make some testy calls to prove they're talking bollocks"
