Raus

raus* (rouz)

archaic/noun
1. A parade or street show connected to the circus.
In the old days when the circus came to town, they would set up their tents and go on a raus about town to let everyone know they were there.

Synonyms: autocade, cavalcade, demonstration, exhibition, fanfare, panopoly, parade, procession, show.

* This is an archaic term that I found in a circus glossary. I think it takes its meaning from the German, meaning to get out, and from the English homonym: rouse.
** Rein Raus is a song by Rammstein.
