SSF stands for single swag
forever, meaning that you are having too much fun being
single to even think about becoming in a
relationship. Also it's a good saying after you have recently broken up to show that you don't care about being single.
Friend in a
relationship: Why don't you just settle down with someone, its real great!
Me: I'm on that single swag
forever, I don't need anyone. SSF all the way!
Recently single girl: Thank god I can be on my SSF without that loser
boyfriend.
