What is Heheh?
1.
Just like lol, this word represents laughing in text form. It's not loud laughing like haha, just a chortle.
To reproduce this word, put one finger on the "E" and the other on the "H". Then hit your hands down right left right left right really fast.
Before there was any Internet, linguists used this word in their research articles. For example:
NO’Donnell-Trujillo, K Adams (1983) Heheh in conversation: Some coordinating accomplishments of laughter. Western Journal of Speech Communication
