Thingymajigtus

Thingymajigtus,
that something whose name escapes me,
Oh, thingymajigtus,
that something on tip of my tongue.

Why can't I remember
what I can see clearly in my head?

Thingymajigtus,
one of seven sins of memory.
In case you forgot what this word means,
it means thingamajig in Latin.

Thingymajigtus,
some know it as whatchamacallit.
Oh, thingymajigtus,
that something on tip of my tongue.

How can I repossess,
my long bygone high mental prowess?
Thingymajigtus,
some know it as whatchamacallit.
In case you forgot what this word means,
it means thingamajig in Latin.
