Get the onosecond mug.
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.
