Futurama
Earth is invaded by a race of intelligent cats.

A fictional cultural term from the show's alien lore, but functions in the dialogue as an untranslatable bond-word similar to 'soulmate' with a legal and biological dimension. Used earnestly by characters, never ironically.
Used exclusively by robots toward humans in this dialogue. The insult is non-compositional in tone: knowing the individual words does not tell you it functions as a fixed derogatory label for organic life, equivalent to calling humans 'flesh sacks'.
A coined word in the script formed by blending two Spanish nouns. The humor relies on recognizing both component words while being surprised by the merge. Appears as a plot-revealing correction of the word 'tentáculos'.
A nautical term repurposed as a comic action command. The phrase is transparent to sailors but opaque to general learners since 'popa' is specialized vocabulary.
Functions as a fixed dismissive expression adapted with 'metálico' to fit the robot speaker. The underlying phrase 'morder el trasero' as a defiant insult is the non-compositional element: it does not literally mean to bite, but to get lost or go to hell.
