A special packet designed to shut up an Internet hOSt. The Internet Protocol (IP) has a control message called Source Quench that asks a hOSt to transmit more slowly on a particular connection to avoid congestion. It also has a Redirect control message intended to instruct a hOSt to send certain packets to a different local router. A "super source quench" is actually a redirect control packet, forged to look like it came from a local router, that instructs a hOSt to send all packets to its own local loopback address. This will effectively tie many Internet hOSts up in knots. Compare godzillagram, breath-of-life packet. [Jargon File]
