Lie to do good

A playful, non-violent insult used between young people. The literal meaning gives no clue to its function as a general-purpose put-down. Common in Argentine youth speech.

The diminutive suffix -ito on 'rapper' adds contempt or condescension. Used here to belittle a character. Diminutives in Argentine Spanish carry a wide range of tone from affection to mockery depending on context.

A fixed phrase meaning the speaker has no hostile intentions. Transparent to a Spanish speaker who knows 'son' (sound, tone) but the fixed phrase meaning is not compositionally obvious to most learners.

A vivid fixed expression meaning to be expelled or fired unceremoniously. The image is of being physically deposited outside by your little feet ('patitas' diminutive of 'patas').

Latin diplomatic term used humorously here in a domestic context to declare someone officially unwelcome. The comic effect comes from applying formal diplomatic language to a household argument.

Used humorously here to describe a personal decision to stop helping someone, borrowing the language of labor disputes. 'Quite' (from quitar) = withdrawal. The phrase sounds official but is applied to a domestic setting for comedic effect.
