I'll (very) occasionally use it as a kind of shorthand for "I've sighted you, and I'm going to follow you in" - usually for the jump plane doing a straight in approach to let him know he can have first go without clogging up the airwaves with a detailed call.
Simpler and quicker to say "ABC turning base, number 2 to the Cresco" or whatever following his call.
So unfortunately it's guilty as charged m'lud!
But I'll agree after #2 it becomes pretty stupid in a CTAF.
