Slang noun used and understood primarily by Brummies (people
from Birmingham, UK), Yam Yams (people from the nearby area of
the Black Country) and other Midlanders. It is a noun used to
describe the action of rolling forwards on the ground. It is
often described as a 'forward roll' by the rest of the country.
Brummies will often say 'gambowl' instead of 'forward roll' and
very few people outside of the city seem to understand this
term. The spelling of gambowl is a debate in itself, as it is
rarely written and mostly used in speech. Variations of this
spelling (gambowl) include: gambole, gambol and gamboul. There
is a Facebook group campaigning to promote awareness of the
word, entitled 'it's not a foward roll, it's a ******* gambowl'.
That was a very nice gambowl you did just now. (That was a very
nice 'forward roll' you did just now.) These gymnasts haven't
done any gambowls yet! (These gymnasts haven't done any 'forward
rolls' yet!)
