Periodic 

The feeling of craziness, confusion, or emotionally instability during a women's menstrual cycle.

My girlfriend feelings are so unpredictable; anger, sadness, and confusion are all so periodic.

Her periodic feelings are always something to run from this time of the month.

Periodic Table 

An amazing table of elements that shows Hydrogen (element 1) to Oganesson (element 118). The farther to the right and up you go on the table, the less reactive elements typically get.

I have the periodic table on my wall.
