Seg
Short for segment, segamatron, seggie, segmeena and segatron (a variation on segamatron), a Seg is a creature of very small stature, likened to a hobbit, of JRR Tolkien fame. They feed on blackcurrant cordial and baked potatoes, and move around in a shuffling manner. They are extremely rare and have often had other animals, such as kia, the wife of the famous willow mistaken for them.

SEG
Lame self-created nickname by a faggoty 12 year old and clung to throughout adulthood, as if it is interesting or exotic. Possibly copied from an obscure Star Track character or a monster from the early 90's Power Rangers.

Seg
Seg = 539. 539 is 1337 in hexadecimal form. Too many people were found to be using 1337, therefor the truely 1337 have turned towards their base 16 saviour, hexadecimal numbers!
Seg, or 539, can be used instead of the word 'Sex', as well as meaning 1337. eg...

-I'm so 539sy (I'm so sexy)
-OMG 539 (Oh My God, 1337)
-539z0r HaxXz0r (1337 hacker)
