Around 50% of people on Twitter believe 'Bonfire Night' is spelt 'Bombfire Night'. Or it seems that way.
The horrendous misspelling has been trending on the social network, on the afternoon of what should probably now be known as "Guy Forks Night" or "Fear Works Night".
Many on Twitter expressed their dismay at the error.
Here's a selection of the best Tweets on the year's worst spelling:
