Something that really annoys me in the Greek language (yes, even though I hardly know any Greek) is the overuse of the word lipon. It is the Greek equivalent of the English so, well then, etc. - and some people really, really use it a lot when they speak here. I may not understand a single damn word someone says, but if they say lipon twenty times they annoy me. I guess the way it sounds reminds me too much of our English ummm, and people who say that with any frequency annoy me too.
With Greeks I imagine it is a way of saying "Hey, I really don't have anything more to say but I am going to hold on to your attention and this is my way of figuring out what other bs I want to talk about".
