"Tumble" is a slang word used by Kenilworthians (those from Kenilworth, UK), and is said when someone makes a joke that nobody laughs at.

The word originates from the way that in TV shows and Films, when somebody makes a bad joke a piece of tumbleweed rolls past.

The word tumble can also be used to describe someone who makes bad jokes, or someone who is generally perceived as a bit of a "loser".

Also, a situation which didn't go as planned can be described as a "tumble".
