“F.”

That right there is literally the entire performance of this recent piece of cyberlore. This weird custom arose from the video game Call of Duty: Advanced Warfare, in which the player (if playing on a computer) has the option to go up to a fallen soldier and “press F to pay respects.” The game was released in late 2014, and for some reason, towards the beginning of 2015 users on sites like Reddit started commenting with “press F to pay respects” whenever death or dying was mentioned on the site. This soon evolved into users simply shortening it to “F,” and now most Reddit users will know what someone means if he/she comments with that single letter. I frequent Reddit, so I kind of picked up on this a while ago, but I love how simple yet inexplicably hilarious it is.
