Belek tiu

"Belek tiu" was a phrase used by the Yuuzhan Vong, often spoken in the presence of those in a higher position of power or respect than the user. It was accompanied with putting both fists on the opposite shoulder, and was meant both as an apology and as a way of asking permission to continue speaking. During the Yuuzhan Vong invasion of the galaxy, Tu Shoolb frequently used this phrase in the presence of Prefect Da'Gara.
