Many Brummies use the term ‘gambowl” instead of forward roll’, and few outsiders seem to be able to comprehend this expression.

Gambole, gamboul and gambol are all variations of the spelling gambowl A Facebook group, titled “it’s not foward roll it’s an agambowl”, is working to spread awareness about the word.
