A word originally derived from the german language.
Whilst originally describing the process of making a knot during
sausage production it now has the meaning of tieing ones own
penis into a knot to prevent urin from leaking out if there should be no toilet available. It is used as a sarcastic
mean to brighten the mood if one member of the friend group is unable to find a toilet. Instead of doing the obvious and telling him to seek a toilet or oppotunity to
pee elsewhere the friends give him the advice to perform a "Wurstknoten". The for english speakers unknown nature of the word is used to create confusion.
"No toilets? Well, seems like you gotta
make a Wurstknoten."
"Had to
pee but then I
made a Wurstknoten, I should be fine for at least another hour"
