czaisz?

This one goes out to Skippo in memory of one hot summer, IRC and Polish trivia, which forced me to research Polish slang. In the course of my research I stumbled across a list of interesting slang expressions compiled by the students of the IV C class at an unnamed "Liceum" in Poland. Wielkie dzięki, whoever and wherever you are now.
