A fairly new but very popular oktoberfest song is "Cowboy und Indianer" by Olaf Henning, better known as the "Lasso song". During the chorus "Komm hol das Lasso raus" (“Come on, get the lasso out”) people move their hands in the air imitating lasso swinging cowboys.
"Komm hol das Lasso raus
Wir spielen Cowboy und Indianer
Wir reiten um die Wette
Ohne Rast und ohne Ziel"
(Olaf Henning, "Der Lasso-Song (Cowboy und Indianer)")
