Cosmo the Seedarian 

Tails' girlfriend on sonic X. they start to develop feelings toward each other during the course of season 3. She comes to warn Sonic & friends about the metarex, a group of alien robots that steal planet life. In the end she transforms herself into a tree and envelops herself around the metarex planet to immobilize and stop them from destroying the galaxy. This gave tails the opportunity to destroy the metarex for good with his sonic cannon but at a price: cosmo's life. The fact that Tails had to kill the one he loved makes many fans consider it the saddest anime moment in history.

(shot destroys the metarex and cosmo)
Tails: COSMOOOOOO!!!!!!!!!!!!!
Cosmo: tails whenever you miss me just look for me right beside you.
(cosmo's spirit kisses tails then immidiately dissapears into the afterlife)
RIP Cosmo the Seedarian

Septenarian 

A septenarian is a person who identifies with one of the seven LBGTQIA identities. Since this community identifies what they are not, non-binary, with the term binary as a base 2 number, they should be identified as what they are in the same base number system. There are seven idenities in LBGTQIA, therefore base 7 is used or septenarian.

My friend is a binary male, but I'm a Septenarian.
People who do not identify with either binary gender are Septenarians.

Semitarian 

A semitarian is a part-time vegan or vegetarian: too much of a wuss to go 100% in but they put in the half-assed effort. They may eat only some types of meat (like oyster vegan or pescatarian), they may consciously choose not to eat meat on certain days (Meat Free Monday), or they may only eat meat on certain days (cheat meal). They may be semitarian for health reasons, simply not care, or find full-time veganism or vegetarianism to be too time-consuming or difficult.

James: I've been vegetarian with one meat meal exception a month.

Sarah: That's semitarian...
James: No, it's vegetarian with 1 meat meal dammit. I don't like labels. I'm a millenial!

It's Meat-Free Monday! Time to flex my semitarian muscles.

Maybe I just dont care THAT much about veganism. I'm doing my part eating meat only on rare occasions. It would be more impactful to make a ponzi scheme for veganism. The results would be exponential. Until then, I'm semitarian.

My doctor told me I have to reduce my meat intake to reduce my risk of chronic preventable disease. So I cut out all meat--except for burgers.

Semenalia

Collectibles, antiques, crafts, and items of interest that are somehow associated with seminal fluid, ejaculation, or the pure joy of jacking off.

That cum rag that you leave under your mattress is disgusting semenalia.

Cellular-semenation

When giz is placed onto a random cellular telephone. When the phone is used at a later date, it is sticky and does not work properly.

Man, my phone has had some serious cellular-semenation done to it. There are only a few people who would do such a thing: Roger, Lee, and Ben.
