1) Bob: Hey, did you see Avatar in 3D? It was amazing!
Joe: You mean that movie with the blue aliens? No way I'm seeing any movie about effin' smurfs!
2) Illyria: All I am is what I am. I lived 7 lives at once. I was power and the ecstasy of death. I was god to a god. Now, I'm trapped on a roof. Just one roof, in this time and this place, with an unstable human who drinks too much whiskey and called me a Smurf.
-Angel, Season 5, Episode 17, "Underneath"
A DoS attack in which there are three parties: the attacker, the victim, and the intermediary. The victim is usually one entity on the internet. The intermediary is a network of some kind. Basically, the attacker forges the packet headers of ICMP request packets so they look like they're coming from the victim. He directs the packets at the intermediary (network). Every machine on the network must reply to the request, so they all reply, but their replies are directed to the victim. That causes the victim, and the intermediary usually, to suffer network congestion, etc. etc. etc. That's a basic definition, but oh well.
