When you are doing something that makes sound and you don't want other people to know you are doing that activity. So you try to cover up the noise you make with another thing that makes noise.
When you poop you turn the bathroom fan on to create a sound barrier.
When you masturbate and other people are in the house you turn the T.V. louder.
When, in a relationship, farting in front of each other is not acceptable. Breaking the sound barrier is the point at which the first fart takes place in front of the significant other.
I always have a tummy ache when I leave my boyfriends place.
Why?
Because we haven’t broken the sound barrier yet and I have wicked gas.
n. software that is no longer sold or supported by the original publisher / developer, often found as free downloads on the internet because it cannot be obtained elsewhere. Not legal, but often seen as morally acceptable because the company that made it is no longer selling the title, nor releasing it as freeware, therefore abandonware is "keeping the gamealive", so to speak.
Doom II is not abandonware because idstill sells it, while The Incredible Machine is not sold, therefore is abandonware.
