Apple recently pushed out a new update for its iPhone users. The update, iOS 9.1, boasts such updates as Live Photo improvements, improved CarPlay stability, and better multitasking performance. But, who cares about that? You’re downloading it for the new emojis.

The update gives users access to over 150 new emoji icons. Some of these are long-awaited additions, while others are more surprising. All of them, however, help us on the path to achieving humankind’s ultimate goal: wordless communication. Like words in any language, emojis carry both denoted and connoted meanings. Here’s a guide for using some of the update's best new emojis ("official" names found on Emojipedia.org).

Name: Jazz Hands. (According to emojipedia.org, this little guy is called “hugging emoji.” Emojipedia is mistaken.)

When to use: Always. There is literally never a wrong time to use this emoji.

What it says about you: You’re the bee’s knees. The elephant’s eyebrows. The cat’s meow. Absolutely jazzy, daddy-o.

Name: Coffin

When to use: When you literally can’t even. When something is so funny you “are dead.”

What it says about you: You are dead. RIP you.

Name: Alembic

When to use: When talking about chemistry. When you don’t know what an alembic is.

What it says about you: You’re a science teacher. Alternatively, you’ve seen "Breaking Bad."

Name: Unicorn

When to use: Never. Unicorns aren’t real.

What it says about you: You’re either 12 or had trouble letting go of your childhood. Alternatively, you’re Lisa Frank.

Name: Hole

When to use: When you need to make a quick exit. When you are completely empty and lacking any describable emotion.

Name: Sign of the Horns

When to use: When you’re too punk rock for something. When you’re making fun of someone who thinks they’re too punk rock for something.

Name: Middle Finger

When to use: When you’ve run out of ways to insult someone.

What it says about you: You lack creativity. You probably waited years for this emoji and you finally have it. Good things come to those who are unoriginal.

Name: Thermometer Face

When to use: When you’re sick, but not “medical mask emoji” sick.

What it says about you: Someone probably asked “Where were you today?” and you needed a way to succinctly excuse your absence. At least you’re quick on your feet, right?

Name: Slightly Frowning Face

When to use: When you’re sad, but not “disappointed face” sad.

What it says about you: You’re pretending to be sympathetic. You really don’t care about the sob story you were just told, but ignoring it just seemed too cold.

What it says about you: You probably got yelled at by your mother for rolling your eyes at her on more than one occasion.

What it says about you: You need smarter friends.
