For me, it is when they make guys look like freaking chicks and I can never tell which one they are. This goes for Haku from Naruto and some guy from Sengoku Basara whose name I forgot.
EDIT: Also, chicks with extremely oversized breasts.

I hate how the English dub voice actors take a dramatic pause before saying someone's name at the end of their line. 20 episode filler arcs are pretty annoying too. Bleach is notorious for performing both very often.
