Kill switch

A kill switch, every doomsday machine has one, I guess. It's the last resort off button, and a huge plot device. Robot going crazy? Kill switch. Inator foiled by a teal platypus? Kill switch. Machine gains sentience and greatly dislikes it? Kill switch. It's that easy!

"Bro, help! My vacuum is turning on me and becoming evil!"
"Does it have a kill switch?"
"Uh... no?"
"It was nice knowing you."

Cat

The best animal to walk the earth. They yell and slice things with their toe knives. They can get high via catnip and eat meat pebbles. They poop in boxes full of sand. We clean, feed, and care for them. And they are ungrateful. Yet we still love them.

"Oh hey, cute cat!"
"Thanks, he absolutely hates me."
"Ah..."
"And also my couch is ruined forever."

astropel

The name means lover of the stars. They are generally curious and interested in what you have to say. With the nickname of Astro, they sure are rare to find. (Especially considering that this is the only definition at this moment)

Astro: "How's it going?"
Person: *Rants*
Astro: *Listens*
Person: "Wow, thank you astropel, you sure know how to listen to my problems."

Joseph: "o-kay..."
