Z-Worst

1. When a person takes no responsibility for there actions or behaviors, choosing instead to blame others or his genetics.
2. A parent who also needs constant affirmations of love and appreciation for shit they supposed to do, and then guilt your ass!

Example 1:
1st person: Man, why you always broke?
2nd person: Hey dude, not cool, you know it's my genetics, it,s not my fault.
1st person: Dude, you are Z-Worst!!!
Example 2: Dad: I paid the rent, utilities, and went to work today, and nobody thanked me, said they love me today. What's wrong, don't I do enough? I guess I will work harder.
Kids friend: Oh man, your dad is Z-Worst!
Kid: I know!
