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 tummyache when I leave my boyfriends place.
Why?
Because we haven’t broken the sound barrier yet and I have wicked gas.
