What does あいつ and こいつ imply in various situations/contexts?


I've read that あいつ and こいつ can mean "that person over there" or "this person
over here", respectively, and also that (at least, as far as I'm aware, for
こいつ) they are an impolite way of referring to a person.

In manga I've seen scanlators interpret こいつ in front of another person as "you
bastard" or "you bitch"... but also that if referring to a person that they
are talking about as あいつ, it gets interpreted as just "that guy" or "that
girl".

What scenarios would imply what when using the phrase あいつ and こいつ?




あいつ/こいつ/そいつ is blunt and somewhat rough, but that does not necessarily mean
it's insulting or derogatory. It can also work as a sign of close and frank
relationship with someone. Let me list some situations.

  * It's always rude and insulting if you used it referring to a stranger or someone higher than you.
  * If you're clearly upset, it's closer to "that bastard", "darn you", etc.
  * When you use it to refer to your close friend, it may suggest you can talk to them in an unreserved manner.
  * There is nothing wrong with a father referring to his child with あいつ, although it does sound blunter than あの子.
  * A stereotyped [tsundere](https://en.wikipedia.org/wiki/Tsundere) girl refers to someone she likes with あいつ all the time.
