slash slash undo

Slash slash undo is a meme in the minecraft community. It refferes to the command // undo, but is spelled out just to annoy the server owner. It was made by youtuber Skeppy, who uses it to irritate his friend BBH when trolling or griefing his minecraft server MunchyMC

"Skeppy, just type in the commands, //undo"
"Slash slash undo"
"NO"

Undo my sad

The titular lyric in the song "Undo" by Sanna Nielsen. The lyric in question is often very confusing. Does it mean to be happy? Does it mean to remove all negative feelings? That is an answer lost to time.

Emily: "Undo my sad!"
Fred: "Bro, wtf does that even mean?
Emily: "I have depression.."
Fred: "You don't.

Once you go blue, you can't undo.

The phenomenon in which a normal conversation turns blue, becoming so riddled with sexual innuendo that it's rendered nearly impossible to steer back in a non-pervy direction. Every innocent comment starts to become a dirty double entendre, until eventually the entire conversation turns into a complete smut-fest from which there is no return.

Girl: Ah, who doesn't love stripper zombies in Portland? That'd go down like Jesus on a velociraptor.

Guy: I have to admit, when I first read 'go down'... I had rather blasphemous thoughts.

~ten minutes later, during which this term is invented~

Girl: Hmm, this Urban Dictionary thing is quite fun. Something for the annals of history.

Guy: Two n's - one 'n' is bad.

Girl: Yeah, I always thought that 'annals' was an odd word.
It really could so very easily be another.

Guy: Terribly easily. So, how is the entry? ...Oh, Jesus!!!!

Girl: Once you go blue, you can't undo.
