I have gotten the "I am not amused" look from a few naturals for these:

Not washing my hair in sections. I comb/brush from root to tip plenty of times.
Not using major natural hair product lines (Miss Jessie's, Carol's Daughter, etc). Some people have taken this personally.
Not trying to "define my curl pattern" or "make my curls pop." I don't care if my hair looks like a fuzzy cottonball one day and some waves/curls the next. I am not sitting up "shingling" with curly puddings all day for nobody.
No shampoo, no hair pins, no heat, no puffs... Just buns.
