Itchy & Scratchy & Marge

Used to downplay one's own effort or kindness in response to thanks or praise. Warmer and more self-deprecating than a flat refusal; signals modesty rather than indifference.

Functions as a thinking-aloud marker when someone is about to look at, consider, or evaluate something. Not a question; does not require a response from the other party. Very common in everyday spoken Latin American Spanish.

A compound formed from saber + lo + todo, but functions as a fixed insult or teasing label for someone who acts as if they know everything. Tone can range from mildly affectionate to genuinely irritated depending on context.

Used to float a suggestion in a casual, low-pressure way. Softer than a direct command or a formal proposal. Common in informal conversation throughout Latin America.
