What is Heha?
a way to express your laugter at someone
person 1-a dog let one rip
when you can't decide between hehe or haha, just say heha. only thing is it sounds a bit like a donkey. neh so just use it online.
person one: (does something amusing)
person two: (thinks; hehe? haha?) heha!
A mixture of hehe and haha. Thus
Sam: Oi! That guy just pissed himself.
