I'm trying this out here, but it may wind up on PWEC. Hopefully not.
I was watching my local morning news today. They did a segment on an initiative being pushed by PETA to replace animal references connected to negative traits in or activities of humans. According to them, using these words demeans the animals and promotes "human superiority" (their words, not mine...they were carrying signs). The words and their recommended replacements listed in the report were:
chicken - coward
pig ------- repulsive
rat ------- snitch
sloth ---- lazy
snake -- jerk
Now, grammatically speaking, pig and sloth becoming repulsive and lazy doesn't work. Pig and sloth are nouns and repulsive and lazy are adjectives. They're simply not interchangeable parts of speech.
Unrelated to the above, I was eating some Kentucky Fried Coward yesterday when my cat walked into the room with an enormous snitch in its mouth. I didn't want him to eat the snitch, so I took it outside. No sooner had I thrown the snitch into the woods than a jerk snatched up the snitch and slithered away with it. Copperhead Jerks and Cottonmouth Jerks are very common around here, but this was just a common Garter Jerk. Anyway, when I got back inside I found that my cat had eaten my coward.
