This is when a female that you know or in your life that is extremely bitchy and mean like she’s always on her period but for one month out of the year she is extremely nice to you and is completely a different person. But when that month ends she goes back to being a bitch
Christian: Yo dude so what’s up with your mom

Ayden: Dude she’s finally on her un-period this month because it’s her birthday month
Christian: damn bro that’s lit my sister is currently on her un-period as well she’s hella nice to me

Ayden: aye bro that’s fucking lit
Christian: yeah fucking tell me about it
