luka
"Luka" is slang in some Latin American countries, particularly Chile, meaning "a thousand pesos."
Here, 'luka' is colloquial for one thousand pesos, used informally to denote currency in street language or casual conversation.
Compré un par de zapatillas nuevas por una luka.
I bought a pair of new sneakers for one 'luka'.
In this context, 'lukas' refers to multiple thousands of pesos, again illustrating its use as an informal term for money in plural form.
En ese negocio nunca venden nada por menos de cinco lukas.
In that shop, they never sell anything for less than five 'lukas'.
Here, 'lukas' is indicating a significant amount of money (thousands of pesos), showing its versatility in describing quantities of currency effectively.
