A suffix that enhances the 1337ness of a word or statement. Common -x0r words are h4x0r, sux0r, fux0r, r0x0r, b0x0r, c0x0r, dix0r, jox0r, and sex0r. Any word that ends with a -cks sound can easily adopt the -x0r ending. See also z0r, the similar suffix used for words that do not have the -cks ending. (pwnz0r, etc.)
- omg!!!!1111111oneone i am t3h h4x0r

A substitution for the suffix "-ck". eg, hax0r, fux0r, chix0r, sux0r.

When using the x0r construct, the "-er" suffix becomes superfluous. Hence, "hacker" does not become hax0rer; rather, the terminal -er is dropped.
d00d, if i was a better hax0r, that chix0r would sux0r my dix0r.

In mid-90s hacker slang, a common superfluous ending to certain verbs: hax0r (or h4x0r), sex0r (or s3x0r), fux0r. Can be combined with other endings: fux0red.
