Worstie 

It's like a bestie, but someone who is really bad at being your best friend even though they are still your best friend.

Rob is my worstie because we are best friends, but he is really bad at it.

Worstest 

The worst of the worst into the worst of the worst. Worse than the worst.

The worstest thing of a party is the hangover the next day.

worsties 

Opposite of besties. Worst enemies; nemesis's. Most often are in competitive roles, differ radically in ideologies, or simply do not like each other.

Jenn and Jane were besties, until Jim came along and pitted them against each other. Now they are worsties.
