Bogna (not to be mistaken with Bogdan, which is a typical Polish male name) is a very rare Polish name for a girl; therefore, if you happen to chat with a girl by the name of Bogna without actually seeing or knowing her, you must remember a few things. First and foremost, there is a good chance she's pretty; secondly, she's either rich or her parents just have a taste for rare names. Finally, name-days for most Poles are very important. Her name-day is on the 20th of June and 23 of July, so if you want to get to know a Bogna you should never forget this.
A POLISH GUY: So what's your name?

A POLISH GUY: Is it short for anything?
