This is a strange request in a unicycle forum, but I don’t know any native Germany speakers locally so please bear with me.
When I lived in Bavaria many years ago my kids had a babysitter who taught them “hände hoch!” to raise their hands. Very handy when dressing kinder of all sizes.
Is there an expression auf Deutch for “hands down”?
My source agrees with kamikaze. Apparently “hands up” is a common phrase in German like it is in English with the same dressing or robbery connotation. The “hands down” expression apparently is not common in either German or English.
