Jim: Wow, Stacey and I were talking last night and she started going on and on about communication, being open with my feelings and all that crap!
Larry: Man, don't you hate it when chicks bring up all that relationshit!
Laura: Kevin and I got into it about how his ex was more touchy, feely than I am. I can't stand this relationshit!
b) Both people in the failed relationship don't want to be there
c) One or both of the relation-ers want to decapitate the other member of the relationship.
Thus, it becomes a relationshit.
Often occurs when a significant other steals/lies/cheats/becomes clingier than plastic wrap or you JUST START TO HATE THEM.
Rebecca: I hate the way he breathes. I hate the way he eats. I hate the sound he makes when he watches football. I want to hit him with a car the majority of the time i see him.
Heather: You got yourself a relationshit.
