Fart barrier 

The fart barrier is passing the point in a relationship where farting in each other's company has become accepted. Thus strengthening the relationship and bond of the couple.

I farted in front of Jules the other day! We finally made it through the fart barrier!

Fart Barrier 

A mental barrier set in place to govern when it is acceptable to fart. To fart before it has been observed "ok" to do so, in a given public surrounding, would be breaking the fart barrier.

Fart Barrier 

The fantastic adventure movie featuring Harrison Ford, Denzel Washington, Kevin Costner, and others. In a flatulent fantasy wonderland, Ford traverses the complexities of real relationships by determining the best time to drop his first audible and smellable fart in the presence of his one true love.

Dude, Indiana Jones was cool, but 'Fart Barrier' was Harrison Ford's best movie.
