No Side in a rugby game?

Answer 1

Throughout the game either one side or the other has possession of the ball. At the end of the game the referee calls "no side" to indicate that neither side has possession of the ball thereafter.

Answer 2

There is no such term in Rugby. You may be thinking of the try line, the line at each end of the pitch on where the goalposts are erected.
