When using Discord, if a user sends a .gif file and then writes 's/e/x' it will turn the gif into an image with instructions on how to pull off the Discord S/E/X hack. This is caused by the fact that every gif is technically a Tenor image, and s/ is supposed to mean substitute. The s/e/x message technically means 'Substitute the letter E with the letter X.'
The tenor link becomes a 'txnor' link, which shows the image. Going to txnor.com shows how the creator of the hack made the hack.
Person 1: Hey, send a .gif file and type S/E/X. It'll cause the Discord S/E/X Hack!
Person 2: That won't work, would it? *types s/e/x*
*image pops up*
Both: WTF DISCORD SEX!!?!?!?!?!?!
Literally the worst Discord server ever, it's quite possibly worser than anything. It has bad mods, a cancerous community and almost everything that is cancerous. It sucks balls, fuck it to hell.
Person 1: Hey Dude! I found some new cool friends at Jameskii's Discord Server!
Person 2: Really!? That server sucks so much!
