A room in Germany, more specifically, a "Claudia kemmer" is a room offered by a woman with rather dubious morals (who is particularly interested in married men).
I'm visiting Berlin and need a kemmer for a night or two.
The definition of Awesome, Straight up bad ass, So awesome that if you combined superman and spiderman you would just get completly awesome. Therefore Kemmer is just the definition of awesome.
Hes a straight up kemmer!
