I feel like Seppos often miss the point of this board, which is relentless piss-taking including self-deprecation.
Being from a culture where people are just continually nice to each other and have always ‘boosted’ each other (or kissed each other’s arses, however you want to look at it), they are initially intrigued by cynical British/Irish/Australian type humour but after a while it makes their heads split open.
