Whatchamacallits

I need to know, Whatchamacallits, what do you call it? I need specifics.

It’s what ever you call it!

Well, that wasn’t very specific! :bash

That is what comes to mind for me also

Is that the same as a Thingamajig?

Noun. whatchamacallit (plural whatchamacallits) (slang)
A metasyntactic term used for any object whose actual name the speaker does not know or cannot remember; a doodad, gizmo, thingamajig, thingy.

Not to be confused with a Doohicky!:Rofl

It’s the curse caused by a brain fart.

I must eat a lot a beans! :dono

Call it house keeping for a cluttered mind
