The phrase: "War In" is a key element to the vs. matches, but can be used as an opposing call-out. War In being the equivalent of Peace Out. In other words, you're just speaking opposite. Another example is Shut up - Close Down. Another one can be Lol (Laugh out Loud) - Ciq (Crack in Quiet), and plenty more to use in conversation.
War In - Peace Out, so flip the fingers upside-down

1. A pastime of many major governments, particularly the United States of America.
2. Organized mass-murder.
3. A way of keeping the population down, the people receptive to propaganda, the rate of technological invention up, and unemployment down.
4. The opposite of peace.
5. A very common state of affairs, possibly due to mankind's seemingly inherent tendency to, when confronted with a problem, find someone to blame and proceed to bash their head in.

1. Self sustaining as long as humanity is aloud to exist and thrive.

2. An extreme act of aggression fueled by the simplest emotion LOVE.
War is self sustaining and peace on earth is a idiocy sustained by the hopes and dreams of fools.
