拎北 Lim Bei, As in “拎北台灣郎” on this t-shirt:
So far I understand it literally means “your dad”, but actually is a slang term (rude, but not actually offensive) for referring to oneself. It also seems to serve to position oneself higher… sorry not sure how to say this in English.
I have no idea if there is any English or German term that would convey a similar meaning and mood.
Best I came up with so far is “This dude’s from Taiwan”, but probably only makes sense to people who know the movie “The big Lebowsky”…
