The Simpsons
Bart, Milhouse, and Martin pool their money to buy the new first issue of Radioactive Man, but their investment and their friendship are threatened when they can't agree on who will keep it.

Idiomatic expression for putting in exhausting physical or mental effort. 'Lomo' literally means back or loin. The phrase is not guessable from the literal meaning alone and would confuse a learner who reads it as a literal description.
Abbreviation used as a dismissive response meaning roughly 'that's your problem' or 'tough luck'. The letters stand for a crude phrase but are used in everyday colloquial speech as a blunt brush-off. A learner would not recover the meaning from the initials alone.
Very common across much of Latin America, especially in Caribbean and Andean countries. Used to express enthusiasm or approval. Heard here as a general positive judgment.
Primarily Mexican usage. Literally means 'twin' in Nahuatl origin, but functions as a casual, friendly address or synonym for 'friend'. Signals warmth or familiarity.
Fixed exclamation expressing that a price or deal is unfairly expensive. Literally 'what a theft', but functions as a fixed complaint phrase. The meaning cannot be recovered from the individual words without cultural context.
Fixed phrase used to withdraw a previous statement after being proven wrong or changing one's mind. More emphatic and idiomatic than simply saying 'me equivoqué'. Common in conversational Latin American Spanish.
Fixed phrase meaning something is offered for free by the establishment or host, equivalent to 'it's on the house'. The phrasing 'la casa' referring to the business is not guessable without familiarity with the expression.
