Season 4 · Episode 9
The Simpsons
Homer and Barney become competitors in the snow-plowing business.

Fixed expression signaling the moment someone stops planning and starts actually doing a task. Equivalent to 'let's get down to business' in the sense of beginning physical or practical work. Very common and used across all registers in Latin American Spanish.
Uses the verb dar rather than tener or estar asustado to express fear. This dar + noun construction for emotions (dar miedo, dar asco, dar risa, dar pena) is a fundamental pattern in Latin American Spanish that cannot be predicted from knowing 'dar' as 'to give'.
Same dar + noun emotional construction as me da miedo. Asco (disgust/revulsion) combined with dar creates a strong expression of physical or moral disgust. Tone ranges from playful to genuinely cutting depending on context and delivery.
The verb arreglárselas is a non-compositional pronominal idiom meaning to manage or get by on one's own. The literal words ('arrange them for himself') give no clear hint of this meaning. Very common across Latin American Spanish in everyday speech.
Fixed idiom meaning of poor quality or importance. The literal words ('of bad death') have no relationship to the meaning. Used dismissively to describe places, businesses, or things considered inferior.
While aflojar literally means 'to loosen', this imperative form is used idiomatically in Latin American Spanish to tell someone to stop being so tense or uptight. The colloquial meaning of 'relax' is not predictable from the physical sense alone.
A play-on-words dismissal used in the episode as a punning equivalent of a ruder expression. The humor depends on 'asfalto' (asphalt) substituting for a taboo destination. Signals irritated dismissal without being outright vulgar.
