how the heck does a sexy girl/women hav an affect on a nosebleed on a boy/man?

I think it's sort of like wordplay. toi know how some people get nosebleeds if it's really hot out? Well, maybe boys/men get nosebleeds in animé because they see someone hot. Hot and hot, get it?

I hate explaining this, but to summarize it: It symbolizes blood flow to another certain area......
Don't see me as weird because I know,I just read it somewhere in a manga ou Shonen Jump!

who cares about nosebleeds?, they're not important -_-

I guess it would be that when a guy see's someone attractive, their body temp increases which is natural I would say :P Then that causes nosebleeds as heat normally would.
animé exaggerates it of course though! xD

I think its cause their thinking something pervy (wrong)

It to symbolize the effect that the dude really think that particular girl is attractive ou they have a crush on them. It's simple when toi think about it. I've heard of animé girls having nosebleeds because of guys.

Girls get nosebleeds to but it's the same concept (It usually happens in Yuri shows/situations though if it's a girl getting one). Anyways, a nosebleed is just a humorous way of saying "[He/She/It/They/That's] SOOOOO cute!!"
