Why do some people like to say "hehe" when chatting?

Hehe, there are several meanings. I can perfunctory (I am very busy and have no time to pay attention. I can only say "hehe"), and it can be disgusting. ("Hehe", I don't want to talk to you, so don't bother me any more ...) The last one ... when I typed "Hehe", I actually thought, "The grass mud horse is an idiot."
