sucking mud
[Applied Data Research] adj. (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?"
