Sever, sunder, split. Separate, divide imply a putting apart or keeping apart of things from each other.

One who never feels the need to pay for food. A person who must keep the back of their car in "their" order, knowing it is actually a mess, making it difficult for others to occupy the back seat. A man who feels the need to be involved in everything and won't let other people have quality time by themselves. A person who feels the need to sit next to a boyfriend and girlfriend in the movie theatre, and then talk through the movie and tries to sound intellectual about it, even though he sounds like a dumbass.
Often a "Severs" opinion and views are drastically skewed and often shoved down a persons throat.
