sucking mud: adj. [Applied Data Research] (also `pumping mud')
Crashed or wedged. Usually said of a machine that provides some
service to a network, such as a file server. This Dallas
regionalism derives from the East Texas oilfield lament, "Shut 'er
down, Ma, she's a-suckin' mud". Often used as a query. "We are
going to reconfigure the network, are you ready to suck mud?"
