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.

Todd: Hey man don't you think we should warn Garret about her?
Mike: Nah, I think a little unbrotected sex is just perfect for him.

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"

come undone

When something hits you out of left field and you can't help but cry. An unexpected solemn event that tends to swell up sad feelings.

Something about the way she said "goodbye" made me come undone.

Undocumented Immigrant

1. A legal immigrant who lost their papers.

2. Liberalese for an illegal. The correct term is Illegal Immigrant. Not Undocumented.

1. Shit! All his papers were destroyed when his house burned down! Now he's an undocumented immigrant

2. Liberal: UnDoCuMeNtEd ImMiGrAnTs ArE aS mUcH oF a CiTiZeN aS yOu
Anyone with sense: Shut up you SJW. They're illegal immigrants, not undocumented

underoath

A Christian band that originated in Florida. They have an interesting sound, which can be described as screamo, hardcore, emo, and metalcore. They're earlier CD, 'The Changing of Times', has a more hardcore sound (it consists of about 85% screaming) than their newer CD, 'They're Only Chasing Safety', which is about 50/50 between screaming and singing.

UnderoathunderOATH
A few of their good songs include 'When the Sun Sleeps', 'Never Meant o Break Your Heart', and 'Reinventing Your Exit'.
