This is what people say when they promised to be somewhere but then went somewhere else and didn't think about the people who were waiting for them.

I flaked because I went to a different party and forgot about the one I was supposed to be at.

I flaked because I had a better snack at the other place.

I flaked because I didn't want to be around people who weren't me.
