How to properly say "cheers" in German

When raising a glass to someone in Germany, it is customary to say "prost" and lightly touch the glasses together. However, it's very important to look the person in the eyes when doing so.

Otherwise, one will suffer from seven years of bad intimate encounters. Or so I've been told.

My expat friends and I try to fit in so we make sure to look at each other in the eyes when toasting each other. We're so careful, in fact, that we look a bit bug-eyed in the process.

I saw the statue below in the Valkenburg Caves in December during the trip with my cousins. That's basically what we must end up looking like during the prosting.

I have mad photo editing skillz. Don't be jealous.
