http://squid.nlanr.net/Squid/1.1/1.1.10/Release-Notes-1.1.txt tells:
--------------------------------------------------------------------
Hierarchy Data Tags

DIRECT The object has been requested from the origin server.

CLOSEST_PARENT_MISS This parent was selected because it included the
    lowest RTT measurement to the origin server. This only appears
    with 'query_icmp on' set in the config file.

Almost any of these may be preceeded by 'TIMEOUT_' if the two-second
(default) timeout occurs waiting for all ICP replies to arrive from
neighbors.
--------------------------------------------------------------------

Your Squid sends ICP-requests to your neighbor-caches.

If the replies from your neighbors aren't in after the configured
neighbor_timeout (default 2sec) the Hierarchy Data Tags are preceded
with TIMEOUT_.

The requested object is fetched with the method which seems to be
the fastest.
