By it's original definition, blowback is the backwards escape of unexploded gunpowder when firing a handgun. In diplomatic terms, it is an unpredicted, negative response against a nation in regards to a diplomatic action that country has undertaken.
The United States, through its underhanded dealings with its enemies, has caused blowback many times throughout its history, leading to bad diplomatic relations and hundreds of millions of people dead.

A slang word used in espionage circles (most famously the CIA), referring to the "unintended consequences of secret operations abroad".
Blowback examples include:

1. Saddam Hussein's invasion of Kuwait - having been helped to power and supplied with weapons and chemicals by the west (the photograph of everyone's favorite Iraqi shaking hands with Donald Rumsfeld says it all).

2. September 11th 2001 - conducted by an organisation composed of operatives trained up by US intelligence for the war against the Russians

3. The Islamic Revolution in Iran, which arose from the bad feeling and anger towards the corrupt, dictatorial pro-American Shah regime, which had been helped into power following the CIA-assisted overthrow of the democratically-elected cabinet of Prime Minister Mossadeq, in response to the latter's domestic policies, principally nationalisation of Iran's oil.

The end result of gassy crap on the back of a toilet bowl.
For example, you go out and eat mexican food chasing it down with the few beers. You wake up the next morning and go to bathroom. The gassy build blows crap on the back part of the toilet bowl called BlowBack.
