OHNOSECOND

That minuscule fraction of time it takes your brain to realize that you've just made a GIGANTIC mistake and reconcile the fact that it is too late.

Bob hit send on his email to Tom, only then realizing that he had copied in the entire company on the x-rated pictures of him and his latest conquest swinging from his sex swing in full leather outfits.

onosecond

The horrible moment when you realise that you have accidentally done something very slightly wrong which has very bad (usually embarassing) implications for you. This is typically the moment of realisation that you just sent a dirty text message to a close member of family, typically your mother, rather than the intended recipient.

Message: "i'm free this afternoon so come over and fuck me senseless, my parents will be out all day"
Recipient: Mum

Onosecond

An Onosecond is defined as the second after you realise you have done something that is embarrassing or bad.

Examples where an Onosecond can kick in:

Text message contents: A sexy message or a picture of your private parts.
Recipient: a family member.

Seeing a typo in an important essay just after you have sent it.

Accidentally revealing a surprise to someone because you were distracted.

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”.
