A slightly humorous abbreviation of he word "reassigned".

The abbreviation puts an emphasis on the substring "ass" and promotes the meaning of your ass changing location (or owner). Contrary to you yourself changing owner.

The underlying message could be that reassignment happens by looking at some form of objective measure of yourself instead of at you as a person.

Or it could be taken to mean simply "reassigned".
