Hey mate, got a light for this fag?
I always like this(Brit,)expression, my Canadian friend said, when leaving a group!
“keep your pecker up” BRITISH, INFORMAL
If someone tells you to keep your pecker up, they are encouraging you remain cheerful in a difficult situation. This phase will soon pass; keep you pecker up, be careful and think hard. Note: You can also say that someone keeps their pecker up if they manage to remain cheerful. The Scot was doing his best to keep his pecker up. Note: `Pecker’ was a slang term for the nose, comparing it to a bird’s beak. If someone is unhappy, they tend to look downwards so that their nose points towards the ground.
