Slap or bunt

[debeau]

If a batter runs through the batters box holding the bat still and hits the ball , is this a bunt or slap .
only important on the third strike if it goes foul .
Note : ISF rules .
Reading the definitions od a slap part2 it describes it perfectly but I have been told part 1 and 2 should be read together .
I judge it as a slap and will continue to do so until convinced otheerwise
