When you're fed up with a situation or person. To move on, or move out. To give up.

Origin: A Youtube video was posted where a 5 year old girl was irate and preaching that she was tired of her house, lack of room for her toys, and mean brother for throwing dirt at her...so she proclaimed repeatedly that she was "going to jen's".
Jill was tired of everyone yelling all night so she she shouted out, "I'm going to jen's!!!"
