Honestly, one of the most annoying cliches in anime for me is how characters always name their techniques. This comes up even in situations where it would never happen in real life, like sports anime or card game anime. In Yugioh, the characters all come up with names for their monsters attacks for some reason. For me, shouting out the name of the technique is disruptive and rips you out of the experience. As a sports fan, I don't expect anime about sports to be 100% realistic, but it's completely unnecessary to name every special technique. The other cliche I can't stand is how so many anime characters feel the need to explain whey move they make in great detail, even when their strategy is inherently obvious to the casual observer. This isn't strictly an anime cliche, but it comes up a lot.
