Sorry, folks, for using the term Hassy.

It's just a "cute" nickname; not a "hipster" or "beginner" thing, in my case.
Some of my least favorites are:
- 120mm film - It is not 120mm wide
- mixing up of the terms f stop and aperture ("Which aperture do I use?") - one is a physical measurement of the hole made by the diaphragm, and one is a setting that is used on the camera/lens. One will almost never need to know or refer to the "aperture" in terms of it's actual size (macro shooters, maybe).
- "Infrared film is exposed by heat." - One of the teachers I assist says this every G.D. time she teaches the IR portion of the experimental class, and it grates on me like hell, because it is passing absolutely horrible information on to students. But even though I have known her for years, I have not yet figured out a way to politely shatter her lifelong belief.....
- treating green box mode as if it is "program" mode (on a modern camera, of course) - it is not, and you will get totally different results if shooting digital (i.e. no ISO control, no AF control, and no ability to shoot RAW)...and why are you using
either of these modes anyhow?
- printing on the back side of a speed easel (so common it makes me sick)
- putting the lens in the enlarger backwards, so you cannot see the f numbers
- buying pre-cut 8x10 mats and expecting your print on 8x10 paper to fit ("Why is there a gap?" or "How do I tape it?)
- "Photography is an art" - No, it isn't. It is a tool/method that has many purposes, one of which is art. Art is art if it is art, not just because it is a photograph (i.e. the technique in and of itself). I realize that this is often supposed to be complimentary, or at least show some sort of pseudo interest/understanding in a conversation, but it really grates. I find it to be a very shallow statement.
Nicknames can sometimes sound stupid, but all but a few just don't grate on me like the totally-inaccurate mixups that can lead to, or be representative of, vast technical or conceptual errors. (I've only seen "'tog" on the Internet, thank gawd!!)
P.S. Oh yeah! And "ATM machine" and "PIN number!!!!"
And let's not forget the diner patron's classic, heard millions of times a day by servers: "A double cheeseburger with cheese."
