Wandelprobe (noun)

1. A choreographed rehearsal that merges orchestra, vocals and sometimes body microphones for the first time in the production of a musical; 2. A vaguely naughty-sounding German word that though it may initially seem like it, it doesn't really lend itself to clever sexual innuendo and don't even think you're going to come up with the elusive and brilliantly definitive "probe" joke because millions of very talented and clever and profoundly disturbed actors and singers before you have exhausted every last possibility a thousand times over; 3. THE COOLEST REHEARSAL OF EVERY SHOW OF YOUR LIFE PAST, PRESENT AND FUTURE; 4. I'm wearing my fake-lifeguard shirt today to make all the bikini models hurl themselves prostrate at my sandy, well-tanned feet; 5. That has nothing to do with Wandelprobe but I didn't have any other place to fit it in today.
