I Move to Strike the Last Word

I move to strike the last word
but the bugs might eat us

Move to strike the last word
in a glass of memory, the color of char

Move to strike the last word
with an emery board and file later

Move to strike the last word
challenge the preposition to a duel

Move to strike the last word
as a flower falls and cracks a toenail

Move to strike the last word
and to finally call him out!
