In several episodes of Assassination Classroom (animated version), characters
develop spontaneous nosebleeds seemingly in response to becoming sexually
aroused. This occurs with a number of male characters, though I can recall at
least one instance where it happens to a female character as well.

Here's an example on Youtube:

Is this a common trope in anime, or something that's unique to Assassination
Classroom? And in either case, is there any rational explanation behind using
this seemingly bizarre method of depicting arousal?

Use of nosebleeds to denote arousal?


This is a common trope in anime. Many examples of it can be seen on Dragon
Ball with Master Roshi:

According to
[AnimeNewsNetwork](https://www.animenewsnetwork.com/interest/2010-07-17/anime-
physics/nosebleeds), it is a long-standing Japanese folk belief.
