I've always wanted the infinite hammerspace that all anime females possess.

Example: Boyfriend says something stupid, making girlfriend whip out bazooka from seemingly nowhere and shoot missile at him (which only makes him kind of black colored for one scene but otherwise he sustains no injury).

Why, with an anime hammerspace, I'd have all the gatling guns I could ever need .

Also, if Filler Arcs have been used enough to count as a cliche, then I will definitely list that under "annoyance."
