Gaslight means: To psychologically manipulate someone into doubting their own perception of reality. Popularized as a relationship term in the 2010s and now used loosely for any persistent denial of someone's. There is no real cause for parental concern; it is descriptive vocabulary rather than risky behaviour. If your teen uses it, context will usually make the intent clear. A short, curious question about where they heard it is usually all that is needed to know whether to follow up.

Why is this section here?
Slang is read by different audiences for very different reasons. The For parents view re-explains the term in plain, non-judgemental language so a caregiver can understand what their child means without needing the surrounding subculture. The For English learners view focuses on register (when it's safe to use), formal alternatives, and common mistakes — what a textbook won't teach you.

- gaslighter80%
Someone who systematically manipulates another person into questioning their own memory, perception, and sanity. A gaslighter doesn't argue with facts — they erase them, reframe them, or act like you invented them. They're the 'that never happened' person, the 'you're too sensitive' person, the 'everyone agrees with me' person. Gaslighters thrive on making you doubt yourself because your confusion is their control. Whether in relationships, at work, or online, spotting a gaslighter is step one of not losing your mind.
- gaslight energy78%
The particular atmospheric charge someone brings to a conversation where you can feel reality beginning to shift before they've even said anything directly manipulative. Gaslight energy is that sense that whatever happened is about to be reframed, that your account is about to be questioned, that somehow this is going to end with you apologising. People clock gaslight energy in the sigh before the explanation, the loaded 'I mean...', the very calm and very wrong recounting of something that definitely didn't happen that way.
- gaslight god78%
Someone operating at an almost supernatural level of manipulation — a master of reality distortion who makes you question your own timeline, your own words, your own feelings with terrifying efficiency. A gaslight god doesn't just deny things happened; they construct entirely alternative histories that somehow feel more real than yours. It's dark, it's impressive in the most toxic way, and recognising one is honestly half the battle. If you're sitting there wondering if you're the problem, you might be dealing with a gaslight god.
