I propose the definition of a new word.
Super Single [soo-per sing-guhl] -gles, noun
An individual incapable of having a serious relationship.
That girl has such bad luck with men, she must be a super single.
This term came about from studying relationships throughout the years. I started to notice I had some friends who had no clue whether or not a boyfriend/girlfriend was going to work out. Somehow I could always tell and so I started to formulate this theory.
