Schwaibe = swears by Polish.
First of all:
SCHWALBE.
Second of all: I swear in Polish in game/forum only in very rare cases when I'm so pissed, the person that made me feel such an anger would suffer heavy damage very shortly after making that mistake.
Appendix: I do not swear in Polish, firstly because I feel it's rude to use yer own language when people from different countries are listening and they don't understand. Secondly - because I also have quite an extensive knowledge of foreign swearings, encluding english ones. (I swear in approximatel 6 languages, while being able to use about two and half).
Edit: This butthurt comes from the sheer fact, that all new players from my country that I encounter are being taught not to use polish in foreign company. -.- That's what party chat might be used for, ffs. -.-
