borta [BORE·ta] noun 1. a muscular man. adjective 2. muscular.
I profess to not knowing much about this word and have never used it. But, I’ve encountered this enough times to be curious and to do some research. As far as I can tell, those definitions above are it. It may also mean someone who has an attractive or a nicely built body but usually in the context of being muscular or gym-fit.
As an example of usage, Fahrenheit, the bathhouse, occasionally has this special promo night for PLUs who go to the gym. If you show to the registration your gym card, you get a discounted entrance fee of 120 pesos instead of the usual 180+ pesos. This special promo was called the Borta Night.
Anyway, I definitely am very attracted to borta guys. Especially those with really nice arms.
