A relationshit is typically defined as a
relationship that you are hanging on to, something that makes you feel like shit and you know it but still hang on to it for reasons unknown or known.
A relationshit is also when both involved are screaming at each other all the time and know it's best to go separate ways but both are too lazy to make a proper break.
Relationshit is a state of affairs of a rather desperate, sad situation between two people.
It can also be used to describe
relationships as a whole, which are usually rubbish because of all the shit, hence
relationshits.
