A coping mechanism used to survive an oppressive, chaotic, system of government which crushes the under classes to which the Švejker belongs.
Švejking usually begins with efforts to obtain certification or accommodation from the rulers in power that the Švejker has some type of disability or infirmity. The incapacity should be such as to render the recipient incompetent and not responsible for his actions.
The Švejker proceeds to carry out his job duties to absurd ends, and throw monkeywrenches into the system periodically. Yet, the Švejker remains continually untouchable because of his "incompetence".
“There are definite advantages to Švejking through chaos.”
On the long running TV Series M.A.S.H., The Character Clinger was the ultimate Švejker.
