Just not cricket

Another exotic example of the bastardised form, from The Hindu's Sportstar weekly. Ted Corbett, in a review of the England cricket team's recent performance, writes:
most amazing of all, the 36-year-old wicket-keeper Paul Nixon who is as people in his part of the world say, "all mouth and no trousers."
In other words he talks a good game while he iron gloves the ball to the ground and always, but always, seems to be in the wrong place at the wrong time.

Handy explanation, but given that Nixon is from Carlisle rather than London or environs, that just isn't what 'people in his part of the world' would say.
