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.
I've been in this relationshit for 5 years now and I have never been so unhappy.
A relationship of two people (no matter the sex), either married or in a committed courtship, who are unhappy, constantly argue, lie to one another, share an unhealthy, toxic dynamic and are just miserable to be around.
“Joe & Diane are both so jealous and make each other unhappy, I don’t know why they even stay together. I never want to be in a relationshit like that.”
