What it means: As in, a "cult following" or a "cult favorite," the word refers to a movie, book, band, TV show, video game, or other form of media that has a small but extremely passionate fanbase.

How you've heard it: "She's a millennial, so she's very entitled."

What it means: Having, or believing one has, the right to something. People use "entitled" to mean "privileged," and that's accurate.

How you've heard it: "I'm empathetic to what she's going through."

What it means: "Empathy" and "sympathy" are often conflated, when they are, in fact, different. To "sympathize" means to feel pity or sadness for someone else's experience. But to "empathize" means to understand what they're going through on a personal level.

What it means: This is often used to refer to scenarios that are very politically- or emotionally-charged. A "hot-button issue" tends to inspire strong emotions from either side.
