YOUR MOTHER WEARS ARMY BOOTS: A Treasure Trove of Insults, Slurs and Putdowns _ by Jordan L. Linfield and Joe Kay (Avon: $9). _ Readers may want to consult this handy reference volume before

visiting their in-laws, attending a baseball game, etc. In addition to the standard swearwords and anatomical references, Linfield and Kay offer such useful obscurities as _ muckworm _ (a

miser), _ siddity _ (arrogant) and _ zuch _ (a stool pigeon). Lively reading--with a few errors and omissions.
