It is when one man tries to break the other man's balls/ ballsack with his own. This is achieved by thrusting the sack at eachother for impact, this violent bloodsport was made famous by the world champion Tengis hailing from Mongolia.

Sack War is when you take 2 grown men from Mongolia and then you have them smash each others sacks in till they break or 1 gives up.. then the loser gets his sack licked till he jizzes.
Tengis: i sack war champion you will never defeat me.. You wish to challenge me?

When a guy, lying on his back, gets suprised - on purpose or accidentally - by another guy who puts his naked ass right on his face, optionally tea bagging him.
At the gangbang party last weekend I was lying on my back giving Tracy some oral pleasure while she was sitting on my face, when Larry decided to take her anally. She was so suprised feeling his cock knocking at her arse that she leaped away, causing Larry to land on my face, his hairy balls landing right into my mouth. Getting a sack of war of my best friend really ruined my weekend.
