A state of tiredness caused by repeated use of mechanical energy, such as skateboarding, but does not represent being sleepy. I common state when skateboarding endlessly in Switzerland. Muscles can become tausig without the brain requiring sleep, therefore the word "tired" is unnecessary, and actually politically incorrect to say- hence, tausig.
PoinDexter: "Hey Jimbo, are you getting tired from skateboarding?"
Jimbo: "No Dude, I slept like 11 hours, just tausig from skateboarding all day."
