a phrase taken out of The United States foreign policy, but meaning here:

as long as I have a common enemy with a given person, I can be friends with that person; I'll take the risk that this friend of mine might betray me later.
Jason: James my man, why the heck are you friends with Robert? didn't he convince you and Alison to break up and the took Alison's virginity anyways?

James: Listen, my enemy's enemy is my friend. What I mean is, Alison and I were already having relationship issue before Robert became a regular at the bar where she then worked. Not only that but Robert and I have a common enemy, whose name is Carl. Robert hates Carl cuz Carl stole his car. And I hate Robert because he borrowed money from me to pay rent on a stupid storage locker and never bothered paying me back.

Jason: so now the you and Robert want to gang up on Carl?

James: Don't know yet, but Robert and I are friends because we do have a common enemy.

Enemy-exchanger

People who exchange telephone numbers with people they hate, never talk to (and never will), or are enemies with. It makes no logical sense yet there's always one enemy-exchanger in a crowd. If you see one, either:
1. Start yelling at them
2. Beat them up
3. Call your nearest mental help facility
4. Run for your life

STAY AWAY FROM THESE PEOPLE FOR THEY ARE MOST LIKELY PSYCHOPATHS.
Can I have your phone number?

No, you Enemy-exchanger!

Enemy

An ally of an enemy is your enemy (not a frienemy or any other coined word from a coined language). Its simple, you know not to trust anyone who's an ally of an enemy.
He/she isn't your friend when he/she is with you. He/she is pretending to be your friend when he/she is with you. An enemy that doesn't want you to know they're your enemy is still an enemy.
