A frelationship is when two friends start dating, but instead of acting like they are in a relationship nothing really changes between them. These situations usually end with one of the two actually starting to have feelings for somebody, thus the frelationship just goes back to a regular friendship. There isn't a messy break, because there never really was anything in the first place.
the gray area between frienship and a relationship, used by all those who are too clueless/confused/unaware of what is really going on to distinguish between the two
Jill: Oh I'm hanging out with Jack this weekend.
Jenny: Oh are you two going out?
Jill: I'm not sure. It's a frelationship. I can't really tell.
Tess and Leith have been in their frelationship for almost 2 years now...I wonder when they'll finally come out and admit their undying love for each other.
either a) one person believes the two are "dating," the other does not.
or b)they couple has broken up, but one still believes that the other has feelings for them.
jimmy and jill broke up two years ago, but jimmy still thinks jill loves him just because she called him once... its such a frelationship!
