Get the GSAmug. Gay-Straight Alliance, or Gender Sexuality Alliance. A high school club that is found in many high schools and secondary schools. It focuses on issues faced by LGBTQ+ students and people and looks for more accepting environments and rights to be had by LGBTQ+ people. They also often aim to educate straight or cisgender people in the school/community about LGBTQ+ people and rights. Often full of nice people who love to be with friends and others and will accept you no matter who you love. A great, gay family. :D
