A cartoon cat made by the Japanese company Sanrio. She is not satanic, she is not trying to take over the world. She is just a cute little cartoon cat.

hello program

If you are required to say hello to someone when you see them, you are on a hello program with them.

The hello list is comprised of all the individual people with whom you are on a hello program.
Girl: Hello

Guy: Hello

Girl's friend: Why the fuck did you say hello to that guy?

Girl: Gaa, he bought my textbook. Now we're on an eternal hello program.

Irish Hello

An Irish Hello is when you sneak into a party and hide for twenty minutes before walking out as if you’ve been there the whole time.
Jack pulled an Irish Hello last night. We didn’t even see him show up. I just looked behind me and there he was mingling with everyone.

hello neighbor

While your girl is at the window, you take her from behind as she waves at passing neighbors or neighbors outside their house unaware that you're fucking her. Fucking your girl doggy style while she waves and converses out the window with neighbors.

hello list

The list of people you have to or want to say "hello" to on a daily basis. Especially relevant for students in university buildings, or coworkers in a workplace. Some people might decide to put you on their hello lists, even if they aren't on yours! Typically, reciprocity is expected.

Dropping someone from your hello list to just a nod when you pass him or her might be considered a snub by the other person.
