Después de un gustazo, un trancazo – After having a blast, you get hit with a huge wooden beam.
OK, I admit I had to do some research on this one! Thankfully my wife is awesome and gifted me Nicaraguan Spanish: Speak like a native! for my birthday. The author, Lee Jamison, provides a great explanation for this one:
As a protection against thieves, some homes have a tranca, or large wooden beam, which sits on wooden hooks just inside the closed interior doors, like a giant latch. The action of hitting someone with one of those huge wooden beams is called a trancazo. Sometimes after enjoying ourselves, perhaps after being on vacation, we must go back to the grind, or even be the victim of some tragedy.
Thankfully, I have yet to receive a physical trancazo, and finally being back home in the beautiful Estelí climate makes this metaphorical trancazo not so bad, either 🙂
