Welcome

Ah! Hippy! I heared about you. Pleased to meet you. Never been to Austria? We even organized a Long John to transform it into a rolling Buschenschank. Sturm and Bradlfettn! (Oliver Schick, try to translate this!)

I can honestly say I'd never heard any of these words before ... Austrian is just a different language from German. ;)

OK, so a Buschenschank is a kind of country pub that serves mainly wine?

At first I read "Buchenschrank", which I found very confusing. :)

Sturm is a kind of not fully fermented wine?

Bradlfettn--pork grease (ugh).

So basically you served some Austrian ... delicacies from a temporary pub established on the rack of a Long John ...

What is a GSIAD? Cannot find it in the Urban Dic.
