I'd say it's going on holiday to a foreign country, finding the one British themed pub owned by an ex-pat and eating there every night as you slowly turn into a lobster.
Bonus point for complaining about the locals not speaking for enough English or saying the local "ethnic" food gives you the shits.
These are just my observations as a brit abroad seeing other embarrassing brits.
Also when you hear a Brit speaking slower and louder in order to be understood by someone who clearly doesn't speak English (or doesn't want to understand, fair play, understand that)
This is unfortunately true and to many men think the size of their penis is directly related to the size of their brolly. One doesn't need a golf brolly to walk down a crowded high street
If too many people use an umbrella at once, it angers the weather god, who whips up a strong wind to turn all the brollies inside out, and blow lightweight people into the road.
