Literally a common Mexican bread roll. Its use as slang for white people is informal and regionally specific to Mexican Spanish. The humor in the dialogue plays on both meanings simultaneously.
A loan translation of the English 'hot dog', commonly used throughout Latin America. The literal Spanish words 'perro' (dog) and 'caliente' (hot) combine to form a fixed phrase for the food item. Without knowing this borrowing, the words appear to describe a literal hot dog.
Standard term for a public or official holiday in Latin America. Used to justify taking a day off work. This is the unmarked word for 'holiday' in this context; 'festivo' also exists but is less common across the region.
Refers to a fun, noisy, informal party or get-together. It carries a tone of festivity and informality. Cannot be deduced from its component sounds; it is a fixed cultural term.
