That's the name of Ballard High School's suicide prevention club (short name: SLAM), which this morning covered sidewalks in front of the school with chalky messages of support for GLBT kids. From the Ballard News Tribune:

In the face of five high-profile stories of American students committing suicide last month after enduring harassment from their peers for their perceived sexual identify, members of the Ballard High School SLAM club spent the early morning hours Oct. 4 writing messages of acceptance and love in chalk outside the high school.

The chalk messages, such as "Just be yourself" and "You are loved," are part of the second-annual national You-Are-Loved Chalk Message Project. The project was started in 2005 by a student at Drew University in New Jersey to highlight the extra risk of suicide faced by gay, lesbian, bisexual, transgender and queer students.
