The Simpsons
Lisa develops a crush on Nelson and tries to change him into a better person. Meanwhile, Homer finds an autodialer and starts a telemarketing scam.

A humorous, informal farewell used in this show as a running gag. 'Oler' normally means 'to smell', so the phrase sounds intentionally absurd. It functions here exactly like 'nos vemos' or 'hasta luego', but with comedic effect. Not a real widespread idiom in everyday Latin American Spanish.
Second-person singular imperative of 'pudrirse' (to rot). Used as a harsh, dismissive insult meaning roughly 'go rot' or 'drop dead'. Much stronger than it looks to an English speaker who knows 'podrir/pudrirse'. Often signals outright hostility or contempt.
Fixed temporal phrase meaning 'eventually' or 'over time'. The literal words ('at the long') do not transparently convey this meaning in context.
Refers to someone who acts cunning or tries to outsmart others, often implying they are being sneaky or overconfident. 'Vivo' here means 'sharp' or 'crafty', not 'alive'. Very common in Latin American Spanish.
A common exclamation expressing alarm, surprise, or exasperation. Literally 'Blessed God', but used as a fixed reaction phrase. The emotional weight varies by tone, from mild surprise to genuine horror.
Used as a fixed directing phrase ('follow me this way') rather than a simple locative. The implied meaning of 'follow me' or 'come through here' goes slightly beyond the literal 'over here'.
