It is common in online conversation among some Internet users to use a fictitious closing tag patterned after HTML: . Over time, it has evolved to lose the angle brackets (/sarcasm) and has subsequently been shortened to /sarc or /s (not to be confused with the valid HTML end tag used to end a struck-through passage).[20] Users of the website Reddit frequently denote sarcasm through the use of /s, as shorthand.[21] This usage later evolved into tone indicators.

Wow, I didn't know the /s had an origin story. Pretty cool.

I mean I can barely remember and hate using /s. at least it annoys me that things which to me is obviously sarcasm, cannot be seen as such on the internet. granted when hanging out and being sarcastic it was sometimes a win to get the double take or eh response.

The irony of having to explain your sarcasm punctuation after using sarcasm and punctuating it in way nobody understands.

I like this one ⸮, I'll try to use it, it's more elegant than /s.

That backwards questionmark doesn't work. I'm only seeing a square. But now that I've copied your text I'm seeing it in the quote. Weird.

Ah the interrobang, an elegant weapon for a more civilized age
