I have been browsing a Chinese forum on pentax stuff, and came across some really interesting thing.
They calls their lense name in a very funny name, for example:
165
535
625
there are lots more, can anyone guess which lense they are referring to?
the answer is:
16-50
50-135
60-250
^highlight the above area for answer.
here is the thread me asking why that is:

so they said typing the fully name takes too much time, and even worst if call them by their nick name.
also, they call the three amigos (31, 43, & 77mm limited lenses) the three princess.
31mm as the small princess (or young princess)
43mm as the eldest princess (literal translation would be long princess)
77mm as the second princess
