A pillow placed between two men sharing the same bed, to clearly define the space of each and prevent unintended / unwanted homosexual encounters during the night. Poss. homophobic.
ADAM: I don't want to sleep on the floor. Can't I sleep in the double bed with you tonight?

STEVE: I feel uneasy about that. I miss my girlfriend and might roll over and hold you in the night.

ADAM: Don't worry, we'll put up a gay-barrier!

A barrier that surrounds many high school girls who are too attached to their female friends. Due to the fact that they are constantly surrounded by judgemental girlfriends (who may or may not be giggling), it proves difficult to ask out said girl due to the excess of females surrounding her. Thus the estrogen barrier.
Guy 1: "God damn! How am I supposed to ask out Alicja when she's got her estrogen barrier up?!"

Guy 2: "I hear that the best time to get those women is just before they go to bed at night, or RIGHT after they get out of the shower. Any other time and you're fucked.

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.

Ostensibly a sex-prevention device, the Pillow Barrier is simply a cushion strategically placed by the female partner in order to prevent physical contact during sleeping hours. Quite often, the male eroneously believes he is cuddling an arm or breast, only to wake up and discover that a pillow was the object of his affections.
Yesterday morning, while my girlfriend was at work, I unintentionally ejaculated all over her pillow barrier; I then allowed a lactating cat to spill milk all over it - that was before I gave the dizzy kitten a gentle squeeze, whereby he shat and pissed on it. And she still kept the barrier there last night - evidently, I smell worse...
