Cuban Spanish is a little different to accents in Spain and most parts of Latin America. Cubans speak fast and mumble and the eastern part of the island they eat the letter S and sometimes put where it doesn’t belong. Besides that, in Cuba people use a lot of expressions that are just being used in Cuba. This makes them hard to understand even for native speakers. But don’t worry they will try to speak slowly and clear when they realize that a foreigner doesn’t understand them.
But to appear more local and make some conversations or haggle easier here are some useful Cuban expressions that might help you to get around.
La Guagua – The Bus , people will understand Bus or autobus but this is the most cuban way to say it.
agro – fruit and vegetable market
Cadeca – currency exchance
la cola- is the queue, do not forget to ask for the last person in line

moneda nacional – CUP
Asere- used like buddy
Qué bolá, que vuelta – whats up ? less slang is: como anda? or que tal?
la cosa – yes it means the thing , but is used in Cuba for the general situation and the everyday life of somebody like: La Cosa está mala!
la lucha – la lucha (the fight) is the everyday struggle of people. mostly used when somebody asks how are you? people answer: ahí en la lucha(here fighting)
