The new game that all the kids play on the school laptops when they are supposed to be taking notes or finishing a test. Like it's predecessors Minecraft and Powdergame, it is the new most popular game played as a pass time in public schools. The game just came out this year, and didn't gain much popularity until many famous youtubers such as PewDiePie took notice to it and recorded let's play's. Since then, it exploded and is currently one of the most active MMOs as of right now.

Jun 14 Word of the Day
Referring to women who are sexually or romantically attracted to other women. Applies to both lesbians and bisexual women, as it is only the same-sex attraction that matters, not any other attractions the women may have.

Originates from the Greek poet Sappho, a bisexual woman from the Isle of Lesbos, from which we get the term lesbian.
The sapphic women greatly enjoyed each others company.
