Most I can think of at the moment are derogatory.

A “dog” is a person pushing their horniness to inappropriate levels.

A “cow” is someone fat and slow/stupid.

A “shark” is a savvy business person who edges into taking advantage of people unethically.

A “snake” is a liar and a cheat. Sometimes slang for a penis.

Quiet, shy people are “mousy”.

Someone who tattles to cops/authority is a “rat”.

A “chick” is an old-timey term for a girl/woman that might get you slapped.

A “kitty” is a vagina and also may get you slapped depending on context.

Someone messy/dirty is a “pig”. “Pig” might also be used for a man who is rude and pushing sexual innuendos onto women without their consent.

While to “go the whole hog” means to not hild back, to embrace doing a thing completely.
