hmm, no that is surely not meant with it
It is one of several meanings associated with the term. It was also a reference that the Swiss mountain farmers were milking cows on a daily basis, which was seen as "womans work" by their Swabian counterparts, who lived mostly from grain cultivation back then. But there was a clear accusation of sodomy associated with the term as well. You can look it up on Wikipedia or the Historical Dictionary of Switzerland, if you don't believe me.
Of course, my comment that this can be considered some form of racism was highly ironic.
