A question that implies someone is in a bad mood (Toe stubbing is rhe worst pain known to mankind - if someone were to stub your toe they would be causing you great pain)
Person 1: Gosh, you’re grumpy. Who stubbed your toe? i.e. who ruined your day?
Person 2: You
An adventure which happened during your daily life. Like a stubbed toe which has been affecting everything you did during the day. Outsiders are generally uninterested about your stubbed toes. While people who are in love would rather be stubbed toeing all day.
