My orbit is a bitch on her menstrual
from Ab-Soul – Nibiru Lyrics 1 on Rap Genius
Meaning
The orbit of Nibiru cuts right through the orbit of the Earth. Much like a woman on her period, Nibiru will probably ruin your day when it comes through. .

A menstrual is a period, which disrupts the natural flow a girl would have if it didn’t happen. In physics terms, a period is the amount of time a cycle takes to finish.
