Happy 5

(slang, humorous) An antidepressant.

An informal, mildly humorous term for an antidepressant medication. The phrasing is affectionately sardonic -- it acknowledges the medication's purpose while gently poking fun at both the clinical reality and the cultural awkwardness around mental health treatment. It is generally used by people who take antidepressants themselves, as a way of normalizing or lightening the subject. The lighthearted term carries genuine affection.

A casual, humorous slang term for antidepressants — the little tablet that takes the edge off the darkness. 'Happy pill' acknowledges the reality of antidepressant use with a lightness that can be either gently self-deprecating or used affectionately among friends. The term has softened the stigma in casual conversation, though it also slightly oversimplifies how antidepressants actually work. Still, it's the kind of phrase that makes a difficult topic approachable.
