A nice slogan by one of the most famous sportwears in the world.
It seems to be a slogan also in Switzerland, for sure in the German speaking Switzerland, where the Confederates speak their “Mundart” (Swiss German dialect).
DAS CHASCH VERGÄSSE! (You can forget it!)
The noisy sentence above is quite interesting, especially in the work environment, which is one of the main sources of nice portraits of the most genuine Switzerland.
Whenever a Swiss is cornered by a colleague with a difficult question or a certain activity to complete within a tight due date, he/she starts declaiming the mentioned slogan. Possibly repeating it more than once to chase away any possible doubt!
Are you asking a Swiss something which is slightly outside his/her mindset?
Are you needing something from a Swiss which is not the most common thing he/she was expecting?
YOU CAN FORGET IT!
