slang. [f. tiddle, by-form of TITTLE v. to tickle.] A feather or feather-brush for tickling: a teaser or tormenter; a tickler.
1900. Daily Chron., 21 May, 5 (Cass. Supp.). In Cheapside you were titillated by penny tiddlers. Anything, from a peacocks feather downwards, which is a foot long, and tickles, is a tiddler.
a. 1904. E. Smith, MS. Coll. Warwicksh. Wds., s.v. (E.D.D.). At mops and fairs in the Midlands the favourite tiddler drawn rapidly down the back, made a noise resembling that of the extinct rattle of the policeman. Now the tiddler has degenerated into any light weapon of offence, which drawn across the face or neck, irritates the skin.
