The Simpsons
Lisa and Bart write an Itchy and Scratchy episode; Homer makes up a missing high-school credit.

Literally means a skylight or bright light source. Used ironically to mock someone who has made a foolish mistake or pretends to be smart. The sarcastic tone is key; said with a neutral tone it could be a genuine compliment, but context almost always signals irony.
A Yiddish loanword used as an affectionate diminutive. It appears in this episode as a culturally specific term tied to Jewish identity and family speech, not general Latin American Spanish slang.
Used in broadcasting contexts to mean something is being broadcast live, and more broadly to mean doing something openly or publicly. The phrase is non-compositional when used in the sense of "making something public" beyond its literal broadcasting meaning.
Goes beyond the literal meaning of "finished." When applied to a person or project, it carries the sense of being doomed or beyond recovery. Tone and context shift it from a neutral completion to an expression of despair.
A fixed dismissive phrase used to shut down conversation and redirect to something else. Functions less as a literal request and more as an expression of impatience or desire to end a discussion.
