onosecond

The “onosecond” is the second after you make a terrible mistake. The second when you realize what you just did and that there’s nothing you can do about it, the second when all the now-inevitable consequences flash through your mind. It is the second after you send a sexual text message to the wrong person, after you delete the wrong file, after you spill the secret that you thought they already knew. The “onosecond” is that stomach-dropping, breath-stopping moment when all you can do is say “oh, no”.

Onosecond

That one moment when you realize you absolutely fucked up and there's no way back, that makes you go: Oh, no.
Dan: You look a bit shaken up, man. What's up?

Todd: I really fucked up today, man. I spilled coffee on my work laptop while working and lost a lot of data. I swear, that was the biggest onosecond I've ever had.

onosecond

The onosecond is the moment where you have made a horrendous mistake, but it's just too late to intervene.

The onosecond is named "onosecond" because it refers to itself, that second that makes you say: "Oh, no."

Onosecond

The very second immediately after you make a horrible mistake, and can only wait for the now inevitable consequences. It's the second after you send a text to the wrong person, the second after you drop your phone onto the train tracks, the very moment after holding hands with the wrong person, the point in time when all you can say is "oh no".

In the onosecond, people tend to wish for; the floor to swallow them up, a giant hand and keyboard coming to press ctrl+z, the ability to transform into a flock of birds, who can fly away, etc.
