What is shown
The drawing shows a schematic face in black-and-white outline: a rounded head, bulging eyes with tiny pupil dots, drawn-together brows, and a wide-open mouth. The mouth is stretched into a narrow vertical oval, with teeth sketched in as short strokes. This makes the character look both astonished and choked with laughter, as if the joke turned out to be so funny that holding back is no longer possible.
This style is typical of rage comics, a genre of simple comics in which emotions were conveyed through a set of recognizable faces. LOL Guy's face doesn't carry a complex story: it conveys a single impulse, uncontrollable amusement that goes beyond ordinary laughter. That's exactly why the picture reads as funny and a little unsettling at the same time.
Origin
LOL Guy's creator is unknown, so the character's origin has only been partially established. As far as can be determined, the image first appeared on 4chan's /b/ board on June 14, 2010. One of the posters claimed to have drawn it in MS Paint. This information isn't documented, so the exact authorship remains unconfirmed.
The earliest known use is considered to be a comic posted on Reddit on June 18, 2010, in the rage comics subreddit. In it, a customer tries to return a fake Pokémon cartridge to an EB Games store, and that storyline became one of the first examples of the character acquiring a backstory. The 2009 date sometimes given is not confirmed, so June 2010 should be treated as the reference point.
How the meme spread
Over the summer and fall of 2010, LOL Guy quickly moved from threads into Photoshopped versions and homemade drawings. In August 2010, an administrator of an art forum made a version with his own face, and a page soon appeared on Meme Generator that collected more than three thousand generations over three years. The more people copied the image, the clearer it became that it fit a huge range of captions.
The character also moved beyond the internet. At the end of 2011, Zazzle began selling LOL Guy stickers, which gathered more than fifteen hundred reviews over the following thirteen months. In February 2012, a YouTube creator released a song about the character, and in 2013 DragonArt published a detailed tutorial on drawing him. These things show that the image became not just a picture but part of the broader culture of the early internet.
Typical use and how the joke works
In comments, LOL Guy is usually placed wherever a laughing reaction is called for, along with a short caption. It's used when a joke is especially good, when a user ends up in a funny situation themselves, or to show that someone's reply caused uncontrollable laughter. Unlike many other faces from that era, it almost never expresses malice or judgment.
The humor works through contrast: the face looks both frightening and amused, and that duality is what makes it ironic. The image reads not as hostile but as a caricature of excessive emotion. That's why it's easy to apply in any context, and it rarely offends anyone, which explains its long life in chats and on forums.
