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”.
