When a girl's vagina starts erupting blood, causing her to go into a state introvertness and hostility. Usually, one can differ a period from an uber period by the duration of the pissiness. A girl plagued with the uber period will go through at least a month of being pissed off before returning to normal, ususally with some lame excuse to justify her unprovoked agitation.
Person 1: Yo bruh, you still into that chick?

Person 2: Nah bruh, she hit her uber-period.

Person 1: That sucks nig.
