Something you can't remember the name of.
You know that thing , that whatchamacallit .
by Edmarie Cubille' May 09, 2016
A word used when the actual name of the object in question will not come to mind. Very versatile but often very vague. It is derived from the phrase "what-you-may-call-it" which can be found in T. H. White's The Once and Future King.
