The noun you summon when the real word hides behind the tip of your tongue.

means A placeholder name for an object whose actual name you've forgotten or never knew.

from One of a whole family of nonsense stand-in words — thingamabob, thingumajig, whatchamacallit, doohickey — that English speakers started coining from 'thing' around the 1800s. The '-amajig' bit is just playful sound-padding, filler syllables stacked onto 'thing' to make it feel official, the same impulse that gives us 'gizmo' and 'widget.' No deeper root than that: it's a word built by people refusing to let a forgotten noun stop the sentence.
