Phoenetic description of L338, which is L337+1, also known as Leet+1. When one is Leeb, they are just too Leet to be described in conventional terms, thus, a new category of Leetness must be invented. Leeb people are as Leet as everyone else, but have that small extra something about them which makes them Leeb.
Stacy: OMG!! 8 headshots, I R TEH L337!!!!
Dick: I h3adsh0tted 9er peepz, 5tanding on my h3ad! WooTNESS!
Stacy: D1ck IZ TEH LEEB!!!!!!

*very important word to add to your vocabulary*
(n) noun; Describing a person we all know who has the most lame, false sense of humor imaginable. A key trait of a Leeb is they insert themselves with too much enthusiasm and feel as if their strange way of speaking deserves a laugh or positive attention. They use common phrases and steal each one to add to their vocabulary.

Common terms may be: “kill it with fire” “hella” “big facts baby” “reeeeeeeeeeeee” “feels bad” “vibin”
“Lol I hate working at jacks, no one matches my vibes there, feels bad
“James you’re such a Leeb, please don’t talk to me ever again”

It's a way of pronouncing 1338. "1338" is a notch above "word1337/word".
I'm more leeb then you.

A screw-up. Leeb is a typo of leet, or 1337, spelled as 1338. Generally, it's made by someone who tries to be 1337 but in their declaration of all that is awesome about themselves involves many an uncorrected typo.
"haha duder u cnt tuch me im 2 1338"
