RULE

Teeing ground
As the definition quoted earlier in the book explains, the
teeing ground is a rectangular area two club-lengths deep bordered
either side by two tee-markers. You cannot move one of those
tee-markers, but you can stand outside them provided the ball
is teed between them. If at address you nudge the ball off its
tee with your clubhead, ignore the person who says 'one'. For
a start, it is not 'one' - you simply replace the ball on the
tee and play your shot - and besides, it's a pathetic joke,
which doesn't merit a reply.
If you play a shot from outside the teeing ground, the rules
vary according to the format of game you're playing. In matchplay,
your opponent may ask you to.play the shot again, without penalty.
In strokeplay, though, you incur a penalty of two strokes and
then
have to play a ball from between the tee-markers. Incidentally,
even if you play incorrectly from a back tee, when obviously
there is no advantage to be gained, you are still in breach
of the Rules.
