As you wish, Sir
It´s a limmerick from Hunting season in Bavaria, when a lot of hunters hunt together, we call it Treibjagd (I believe it´s called Battue in english), there are some drivers and they say (or better shout) this limmerick all the time to let the hunters know where they are and not getting shot. So this means just for deer and other wildlife. This kind of hunting as a big sporting event here during end of november and beginning december on every year.
Hurax dax, packs beim Hax! [Hurax dax (there´s no meaning in bavarian language), grab it at the leg]
Packs beim Fuas, zsam foin muas! [grab it on the foot, it has to fall down]
It has no real meaning, so it´s a strange limmerick. But it´s easy to write in regular letters, which is normaly not to create in the bavarian dialect
