what does "of that ilk" mean?

[Bugbear]

My New Oxford American Dictionary states:



Regards,
Rex.

AND I will point out, if it is now a noun in the American language, it can be twisted into verbs, adgetives and all sorts of other horrible things:
Ilked, ilky, ilkified, ilkological, ilkology, ilkography...
Example: Dude! That Pink Death kilt is totally ilk, man.
Example: In the early years of the twenty-first century, kilt wearers from around the world ilked together at XMTS.
