I've been doing this type of work (Spanish transcription and translation into English of jail calls, emails, police questioning, videos, etc.) for three years and have learnt quite a bit about Dominican and Puerto Rican street language. "Janguear" means partying or hanging out. "Pa la recta" is hard to tell. "Recta" is a name given to highways. However, it might be the name of a pub or it might even be one of those new words coined by reggaeton authors. If so, the exact meaning is really hard to find. Educated Puerto Ricans hate reggaeton and have no idea what the weird words in the songs' lyrics mean.
