Noob seizure
When one is attempting to kills a noob in a game such as Call of Duty, and the noob freaks out and randomly knifes/shoots in the air, in most cases ultimately achieving nothing and dying. However, in some bullshit cases, the noob somehow kills you by some incredibly feat of God.
"Haha, what an idiot. I got a free kill cause the stupid had a noob seizure."
"That guy just had a freakin noob seizure and killed me!"
"That guy just had a freakin noob seizure and killed me!"
