Alright if you guys want to rename it so much, lets start seeing misuse in the articles. I'm going over the entire article and here's what I see.
1. The Anime section makes up 75% of the entire page. EACH AND EVERY LAST ONE OF THE EXAMPLES IS CORRECT in that it describes how (or why) they happen and are for the sake of comedy. None of them are about nosebleeds inflicted by physical pain (which I don't think is or should be tropable since it's just a common body injury).
Add the Video games section onto it, and you get 80% of the article. All the Video Game examples are correct because of their association with anime and Japan in general.
The Webcomics section are correct since webcomic artists are usually savvy enough to know about the Nosebleed and will incorporate it into their comics for the sake of comedy.
It's only when you get to the Film, Live Action TV, Western Animation and Real Life (the last 10% of the article) that you can start to question whether it applies or not.
From where I stand, there's nothing wrong with the article name. It's working as intended.
