Die maakt de directory plakkerig.
Zie sticky(8). Overigens wordt de grote T een kleine t als het laatste x-bit (die je vanwege de T niet kan zien) aan staat. Als de sticky(8) manpage niet geinstalleerd is (of in FreeBSD niet bestaat):

NAME
sticky - `sticky' append-only directories
DESCRIPTION
A special file mode, called the sticky bit (mode S_ISVTX), is used to in-
dicate special treatment for directories. See chmod(2) or the file
/usr/include/sys/stat.h
STICKY FILES
The use of mode S_ISVTX is reserved and can be set only by the super-us-
er.
STICKY DIRECTORIES
A directory whose `sticky bit' is set becomes an append-only directory,
or, more accurately, a directory in which the deletion of files is re-
stricted. A file in a sticky directory may only be removed or renamed by
a user if the user has write permission for the directory and the user is
the owner of the file, the owner of the directory, or the super-user.
This feature is usefully applied to directories such as /tmp which must
be publicly writable but should deny users the license to arbitrarily
delete or rename each others' files.
Any user may create a sticky directory. See chmod(1) for details about
modifying file modes.
BUGS
Neither open(2) nor mkdir(2) will create a file with the sticky bit set.
