An ex obviously is the prefix of past, but ex's never understand this. They are hideous creatures who used dark magic making you oblivious to all of their flaws. If you're a man , you were an asshole who didn't deserve a genuine loving person. If you are a women , you are a supercilious, pampered, promiscuous, BITCH. An ex generally tends to have sex with you because they are desperate whores who can't contain themselves. Meanwhile, you're dating someone else they have an epiphany that they have lost something of value and begin to plot a way of destroying your happiness.

The Ex is someone you most likely now Loathe, but at some point loved, or maybe just enjoyed having around, normally the result of a breaking up of a relationship of some sorts.

The word Ex is normally followed by these words..

Girlfriend, Boyfriend, Wife, Partner.

All these do apply..and a few more do too.

The easiest way to become an Ex, is to Cheat -
(mainly meaning to have sexual intercourse with another male/female whilst you are with you main boy/girl/partner etc)

BE WARNED! - your mates will hate you if you perform the above act, and they are friends with the guy/girl you cheat on.

Cheating will normally be accompanied by lies and deceit, in some cases a hidden guilt.
Dan: "Nicola cheated on my last with another guy, she denied it at first..but then the second time I asked her she confessed, I dumped her, sh is now my Ex"

Gary: "Bro, She's a NO-GOOD whore"

Dan: "Well now iv'e seen her true colours, and i'm glad she is gone"

Gary: "Good for you bro, she didn't deserve you, especialy if she was going to treat you like that, you deserve better"

Dan: "Yeah, I do, thanks man"
