ex a departure of a male or female due to certain circumstances. Not being in love anymore, loss of attraction, common interests suck or not having enough time to spend with friends.
He is now my ex because I’m selfish and didn’t want toinclude him to be in my life or to be around my friends.
Some random shit I defined it as: What you say if you didn't want to hear something or see something as if to "ex" or slash or erase it from one's memory.
