The Fart Injection Threshold (FIT) is the exact pressure necessary for a person's "hiney" which is properly and securely mated with a cloth surface (couch, car seat, pillow, etc.) to break through the somewhat permeable fabric with flatulence. If one cheek of said hiney is higher than the other or your pelvis is tilted, the fart will fail to penetrate the fabric barrier and thus pass through the choad channel and dust the back of your testies.
1. Last week I had to put plastic on my couch because some bad children broke into my house and fumigated my furniture. Good thing scientists have yet to discover how to break the Fart Injection Threshold of 3,000 Mil plastic.

2. Yo, my girlfriend has such a sexy butt, I used to always sniff her car seat. That was until her pops told me that he frequently breaks the Fart Injection Threshold of her car seat when he borrows her car to get Indian food!

To itch ones threshold.
To itch ones genitalia.
When someones balls are itching this term is used to make a public statement that you are going to or are currently are itching them.

Comes from the totally awesome soundtrack of Scott Pilgrim vs. the World in the song "threshold" (played by the fictional band sex bob-omb originally written by Beck) at the part in the end when the lyrics go "reaching my threshold" but the word "reaching" is commonly mistaken for "itching"
"maaan my threshold is REALLY itching"

The sociological rule that one person wearing a fedora in a larger group may be stylistically unique, but two or more people wearing a fedora in a larger group renders every person in that group a douchebag.
Check it out - another fedora. What a douchebag.

No, wait - if it was just that one dude it might be cool, but two of his bros are wearing them too. According to the Fedora Douchebag Threshold Theorem, all five of them are douchebags.

The point in a video game wherein the challenge exceeds the fun. Mario Hedonic Threshold or MHT is named for the world's favorite digital Italian plumber, but the term could apply to any challenge a gamer finds sufficiently frustrating. MHT value necessarily varies according to an individual gamer's psychological characteristics and skill set.
Subject M's Mario Hedonic Threshold (MHT) is as high as Rainbow Road. M didn't even break a sweat during that final lap! Subject L's low MHT, however, resulted in a broken TV screen and reports of a researcher being force-fed a Joy Con.
