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.
One of the most iconic straight in F1 racing; part of the Circuit de Spa Francorchamps.
Person 1: What is Kemmel Straight?
Person 2: Bruh, you don't even know Kemmel Straight? Mika and Schumacher had a moment there and Sebastian Vettel has even cummed there.
