look up any word, like bootylicious:
1. lagnificent
The word used to describe a magnificent amount of lag on one's computer/gaming system.
Eg.

"I should've turned down my resolution, my computer is so lagnificent."

Person 1: OMFG I just got killed cuz im lagnificent.
Person 2: Nah, u just suck.
2. Lagnificent
When the lag in a Modern Warfare 2 match is so amazing, all you can do is sit in awe at how you die.
