YH is a less popular internet abbreviation, used for replacing the word “yes” or “yeah” in one’s message.
“YH” first stared appearing in the early 2000’s, on message boards and chatrooms, as well as forums.
It was widely associated with MSN users at the time, with quite a bit of judgement directed toward those who used it, with a common stereotype of a “YH” user being of a preteen girl.
“YH” was first defined on Urban Dictionary in 2005, with some other entries written on the subject since that time.
The abbreviation never truly turned viral, withering as time progressed.
