Brasileña
A pun used as a euphemism for masturbation. It relies on the phonetic similarity between the headword and the phrase a brazo y a leña (by arm and with force), describing the physical motion. (In the Dominican Republic, channel 17 was a widely known adult cable channel).
A: Man, today I am going to watch a flick on 17 (a porn channel). B: Well buddy, looks like you are doing the Brasileña.
