b) A person that is not very good at athletics.

Rhyming slang for an over-patriotic Brit (bulldog shit).

Typical Bulldog:

trumpets the role of Britain in the Second World War, yet who was not alive during that period;

is able real off a list of "injustices" perpetrated upon Britain by all manner of nations from 1066 to the modern day;

has a complete grasp of history, except for the inconvenient bits, e.g. drawing up the map of the modern Middle East or creating an empire based upon an industrialised slave trade;

has a list of great British inventions at the ready which includes the Internet and radar;

does not trust anything European except for Stella Artois, a holiday in I-Beefa (Ibiza) twice a year and their "local" football team which is 100 miles away;

is always one sentence away from "Don't mention the war" or "Over sexed, over paid and over here".
Did you go down the pub last night?

Yes, but I left early. The place was full of pissed Bulldogs singing Land of Hope and Glory.
