That is the sticky bit. One way to set it is to cd to /tmp as root, and
run:
chmod 1777 .

This will set tmp as readable and writeable and executable to all users,
plus the sticky bit will be on. Normally if you have a directory with so
many permissions, any user could come in and delete or alter the files
of another user without them knowing, thus breaking things or adding
covert changes. The sticky bit allows all users to do anything in
creating new files, or altering their own, but disallows them from
deleting or altering files that pre-exist and are not owned by them.
It's a playground with a supervisor, so to speak.
