An obfuscated manner in which your phone company calls you a fucktard. QAM stands for Quadrature Amplitude Modulation which is nonsensical in this context since fiber optic cables are completely digital. Thus, one may only conclude they think of you as childlike and will be mystified by their impenetrable jargon. Perhaps only being able to reply "Nice truck."
Consumer: "Tell me about FIOS."

Phone Carrier: "Sure, True quam."

Consumer: "Oh... I see... Nice truck."
