British for Sexual Intercourse. In Great Britain this is how partners offer themselves to each other. In Texas we just call it "Having Sex"
In the movie "The Bank Job", the hot British girl would offer a roll in the hay to British men of authority in order to gain leverage and information. It was entirely for business and she really did not care about their performance.
