Well, I figured I’d take just a second to list some of the common synonyms for Gigawidget. Here we go…
Doodad and variants doohickey and doomaflobber
Gismo and Gizmo (either spelling is actually correct)
Thingamabob and the variant Thigamajig
Whatchamacallit and the rarely used Whatchamathingaflobber
As always, Send ‘em if you got’em.
