The "sticky" refers to the "sticky" or "t" bit shown in the directory
permissions:

# ls -ld /dev/shm
drwxrwxrwt  2 root root 40 May  7 14:47 /dev/shm

Permissions set up like this enable anyone to create new files and
directories in this directory, but only the owner of a file or directory
can remove them. You'll find that /tmp is set up the same way.
