Keystrokes

[Greta]

In normal circumstances, [keystrokes] is describing the act of typing something using a keyboard.

However, on the internet, specifically [Gelbooru] and other hentai picture sites, its caught on as a meme*. Its used by members who are presumably masturbating to said pictures, and since comments cant be posted with fewer than three to four characters, they just either post keystrokes in [all caps] or many times.

Its used similarly to fap in this regard, which is the onomatopoeia for masturbation.

*A meme is a fad almost always exclusive to the internet that very quickly grows insanely popular.
