Goodbye, hitpael?

Wow, did you ever pay attention to the word "lehitraot" when people say goodbye? You are not the only one who did NOT. It is actually a verb and not a noun. Okay, but why would that matter? Well, if it is a verb that is being (ab)used as a noun, then what is the translation really?

Like always, I made a video:
