A very colloquial version of "Wonderful" in German for less well off Germans. In fact, the speaker may have become convinced of that something is wonderful while seated at the bar. Colloquial for "Wunderbar" or Wonderful.
Das madchen ist wunderbarische.

Es ist ein wuderbarische idee ( see Harvard law blog)

Ich konnte wunderbarische Deutsch sprechen! (see cookinglight)
