Hit your toe or foot painfully against something hard, usually by accident.
From Middle English 'stubbe,' possibly from Old Norse 'stubbi' meaning 'stump.' Originally referred to bumping against stumps, then generalized to hitting any hard object.
The specific pain of a stubbed toe is so intense and sudden that almost every language has an idiom about it—it seems to be one of humanity's most universally relatable minor injuries.
