It's ET cetera. Not "EX cetera" or "ICK cetera". ET. Rhymes with pet, set, and let. Et, latin, meaning "and". "ET CETERA" means "and so forth", or "and the rest". It is a latin phrase used in all the latin-based or -influenced languages (including ours) and means the same in all of them, since it is unaltered from the original latin.
My boss does this one all the time and it drives me insane. "ickcetera, ickcetera". Or even, "And ickcetera." This morning, the Sirius traffic announcer used, "EX cetera".
(see also "EXpecially" or "ICKspecially").
Rant over, please resume normal blog.
