Common manners

In cuba the common manners are very similar to ours here in colombia , although they are much more polite and generous. For example, if you are thirdty and ask for a glass of water at a random house, they will give it to you without hesitation. Some expressions from cuba are : 
"YA VAMOS ECHANDOLA"  that is used when somebody wants to leave
"VOY A DAR TREMENDA BARRA O CAVILLA"  it means to make love intensely 
"VOY AL PISO"  im going to sleep
"ESTA QUEMA PETROLEO" a girl who likes black men.
