A word that stems from the phrase "k thx, bye" (and it's derivitives), which are bastardisations of "ok thanks bye".

This uttering is commonly associated with so-called IRC "lamers" (see lamer) renouned for the overuse of retarded abbreviations (such as the above) during chat sessions.

It is used extensively in IRC geek humour and in-jokes. See the example.
