Response from OP u/pantsarenew:
I have lived here my entire life and have never heard of a coot
Answered by u/GrimmWilderness:
Fun fact: coots are known to be riddled with lice. In WWI, soldiers in the trenches were plagued with body lice, it was a real problem. Aside from being blown to bits with artillery and cut down by machine-gun fire and picked off by snipers and having their feet rot off with trench foot, the poor soldiers were also being eaten alive by body lice.
They would say "I am lousy as a coot."
This is thought to be the origin of the word "cooties."
