Used as a mild insult in Latin American informal speech to call someone foolish or clueless. Less severe than stronger insults and sometimes used in a teasing, not fully serious, tone.
A fixed idiomatic phrase common in Latin American Spanish. 'Bárbaro' functions here as an intensifier meaning 'amazing' or 'fantastic', not 'barbarian'. The phrase cannot be understood from its literal parts.
Used to describe someone who is old-fashioned, boring, or socially rigid. Borrowed as a cultural calque from English 'square'. Common across Latin American informal registers.
'Onda' in Latin American Spanish carries the sense of vibe, wavelength, or current mood. 'Ponerse en onda' means to connect with the current feeling or lifestyle, especially related to music or youth culture. Not deducible from its literal words alone.
An augmentative-humorous form of 'gordo'. The suffix '-inflón' exaggerates the meaning playfully. It can be teasing or affectionate depending on tone and relationship between speakers.
Standard term for a drug trafficker, used seriously in news and journalism, but here used as a mistaken accusation in a humorous context. Knowing the word is key to understanding the joke in the episode.
A humorous nonce verb coined from 'rastafari' using the standard Spanish -ando gerund suffix. Illustrates how Spanish easily creates verbs from cultural nouns in casual speech. Not a standard dictionary entry.
