Let's start with this one. I know a certain gentleman that uses this one a lot, but I don't know anyone besides him ;)
Does anyone of you use that at all? What do you think, what are the origins?
I know this can be looked-up, but that's not the purpose of this group - I'm interested (as a non-native English speaker) of what people think, not actual origins. I reckon it's funnier this way ;)
