When Paul Taylor writes: "One person has ticked me off for having a shouting match with Mike Barr," what does he mean? Is this a Taylorism or a Londonism? In the American Heritage Electronic Dictionary Copyright 1991 it says: [tick off]. (Slang). To make angry or annoyed: ``got really ticked off at her refusal.'' So is Paul saying that someone made him angry for his having a shouting match? Come to think of it, it wouldn't be all that surprising.
