:cookie: n. A handle, transaction ID, or other token of agreement
between cooperating programs. "I give him a packet, he gives me
back a cookie." The claim check you get from a dry-cleaning shop

useful for is to relate a later transaction to this one (so you get
the same clothes back). Compare {magic cookie}; see also
{fortune cookie}.

WANT A COOKIE"....
