SPORTS HELP TO
MAKE OUR TONGUE
The draftees assigned to Camp Claiborne, in Louisiana, got out a glossary of slang terms to describe everyday things in army life, we read the other day in a United Press story.
No doubt, the boys at Fort Ord and Camp McQuaide, in our State, know what the Louisiana lads are talking aoubt when they call canned milk an “armored cow,” and the white fish a “sewer trout,” but civilians are puzzled by the lingo without the aid of a dictionary of vulgarisms.
The Louisiana lads call prunes “army strawberries”; chicken, “crow”; coffee, “battery acid”; hot cereals, “North Dakota rice”; foot inspection, a “kennel show”; insects, “motorized dandruff”; steel helmets, “Mae West bonnets,” and machine guns, “Chicago atomizers.”
Of all sports, we think that baseball has the most quaint and richest expressions. The young men at Camp Claiborner must have been bush baseball players in their civilian days, otherwise we cannot account for the sprightly imagination that provoked them to call army coffee “battery acid.
