Madagascar hissing cockroach 

An evil pest that is kept as a pet by dumbasses that looks disgusting. Cannot cause infestations in cold areas, but tropical climates can have infestations, like FL. Fortunately, those areas outlaw the import of those pests, making the stupid pet roach people upset. Created by satan himself. Feel free to break out the flamethrower when you see one

YouTuber: “Casting Cockroaches + iPhone 7 Plus in Molten Aluminum!”

Dumbasses (probably a TikTok user): “this guy deserves a painful death for killing those poor madagascar hissing cockroaches. Those things are bred to be pets and he bought them to kill them 😢”

Normal person with brain cells: “Cockroaches cannot feel pain or emotions. Kill those bastards!”

Dumbasses: “I am actually crying from that video. I have hissers as pets and I couldn’t watch as he tortured those cute hissers. My hissers can feel pain and emotions, unlike you asshole”

YouTube: “This is animal cruelty. We need to give him a guidelines strike and delete the video!”

What has society become???

Hisser 

A sneaky female fart.

A woman engaged in conversation at a cocktail party cuts loose with a hisser, i.e., she silently passes gas. She will usually try to affect an air of bored nonchalance but, to deflect possible attention to herself, will often transfix the nearest male with an accusatory glare which implies, 'You pig! How dare you do that in my presence?'
