Discussion Forum—A Way with Words, a fun radio show and podcast about language

This news item:  http://www.nbcsandiego.com/news/local/Feces-Flinging-Defendant-Gives-New-Meaning-to-Jury-Duty.html , reminded me of a word and phrase, I heard in southwest Missouri in the early to mid 1960's.  The OED has "blivit" or "blivet" and its first occurrence as, "1967 WENTWORTH & FLEXNER Dict. Amer. Slang Suppl. 673/2 Blivit, n., anything unnecessary, confused, or annoying. Lit. defined as ‘10 pounds of shit in a 5-pound bag’. Orig. W.W. II Army use."  My dad was in the Army during WWII, but, contrary to the OED it was pronounced with a silent 't', BLiV - ee . 

The phrase was "a modified A-1 blivet" which was a sack of shit with a hole in it for slinging around and spreading.  Growing up with dairy cattle, I always envisioned a 100-lb burlap bag which often had mouse holes or larger.

Anyone else heard of these?
