look up any word, like bukkake:
Someone you sit next to in an orchestral setting. These relationships often extend beyond a musical friendship and often can be confused with a more intimate relationship. It is not uncommon for stand partners to share a bed, participate in couples yoga, share food, and cuddle.
"How are you spending your easter vacation?"
