Turtle or tortoise? I ran into this alliterative answer this afternoon: “Totally terrestrial Testudines are tortoises.” (The source for this 5-worder is http://www.ncaquariums.com.)

Today I drew a “turtle” based on a friend’s photo found on Facebook. (Alliteration is contagious…) Then I halved “Turtle” to bookend a double acrostic, and having warmed up with halving mayhem, I inflicted impending insidious impact. (Vowel sounds are assonance, not alliteration.)

Tortoises misnomered meet
Tarryingly in the street
Under streetlamps they compel
Undercarriages to dwell
Run down they won’t praise nor blame
Rather ask you not misname
