Okay so I was on snapchat with my girlfriend (I'm a girl btw) and we were talking about her butt (shut up we are a new couple) anyways she said I had to "claim" it if I wanted it to be mine, could she mean like grabbing it or could she mean eating she ass cause 1.im 100% not down with doing that and 2. Don't even know how, could someone maybe explain a little
