Like the truth, appropriate is self defined. For all our sakes, I'll err with brevity.
I am truly bone tired of the following:
Doing a visual inspection of anyone's tattoos.
Diverting my eyes and struggling to understand a conversation because a tongue implement has now become a speech impediment.
Guessing the circumference of any upper thigh area that I should not have to see.
Wondering why anyone would be so disrespectful to wear that (fill in the blank) to church, a funeral, a job interview, a dinner party, or anywhere in public.
I am a great fan of, "To each his own." Do it, live it, celebrate it.

Everything has its place. You can have it. Please don't make me look at it.
