Well, you could have looked on TV Tropes, but I guess this thread is okay.
1) Older men are always perverts, most likely pedophiles
2) Older women are always either the bad guy or the nicest person in the series
3) If the series is actiony and about a kid, they will defeat an entire army by themself
4) Aliens look human
5) There will always be nonsensical filler stories throughout the series with content that is never mentioned again unless it becomes a brick joke or chekhov's gun.
6) People power up when they scream
7) The bigger your hair, the more powerful you are.
8) Females do nothing to help the MALE protagonist(s).
9) If they find the big bad and he's with his lackey, the main protagonist's friends will pull a heroic sacrifice and fight the lackey while you go to the big bad. Then proceeds the story making it appear that they were killed.
10) In response to #9, right when the main protagonist is about to lose to the big bad, his "dead" friends show up and help him win.
11) If a giant robot destroys a town, nobody questions it, even if giant robots never existed before then.
12) If the story is set in a typical Japanese city, and the main character has unnaturally colored hair (Such as Ichigo having red/orange hair when that's unnatural for Japanese people. Or some of the Sailor Scouts, even), nobody questions it beyond possibly making fun of the main character.
13) It's okay for your 10-14 years old child to go out into the world and roam without any adult supervision.
14) In response to #13, it's also okay for your child to befriend the world's worst pervert.
