ferment 

The act of staying in your room for days at a time, not showering, and avoiding social interaction to the point of becoming a greasy, unhealthy slob. Usually accompanied by heavy use of the internet and/or video games. A fermenter's natural habitat is typically found in the dark corners of sites like 4chan, reddit, and twitch.

Once you start to ferment, it can be hard to get out, usually requiring some sort of wake-up call from the outside world. Some fermenters never get this wake-up call or ignore it, resulting in a lifetime spent mostly in their rooms.

Fermentation can lead to later complications such as depression, anxiety, anti-sociality, obesity, diabetes, and more.

Fermentation

The process in which a woman who regularly partakes in heavy alcohol and drug consumption inserts a tampon into her feminine area and leaves it there for an extended period of time (usually at least three weeks). After enough time has elapsed, another person removes the tampon with his or her teeth and sucks all the accumulated toxin filled fluid from it in order to experience an altered state of mind and body which is said to have no rival.

It's a brand new sensation, and it's sweepin' the nation: fermentation.

Firmentation 

The 3 part process of alcohol conversion to boner; first from yeast/ sugar converting to alcohol, then the alcohol getting a man horny, followed by an erection.

After science class, me and the boys would hit a bar to continue our studies of firmentation in hopes of getting laid.
