1N4N3 (pronoucned in-ayne) is a spoof off of the official word inane. It is commonly used to mean 'utterly retarted' and to completely bash your friends. When using the word be sure to say it with a demeaning and mocking tone.

The fact that it is spelled 1N4N3 instead of Inane gives it a sense of "eliteness" and makes it an honor to use.
1. "1N4N3 Brent"

2. "That woman is so 1N4N3"

That woman is so stupid/retarted.
