Ground Zero 

A state of being wherein you feel as if you cannot sink any lower emotionally, psychologically, or physically.

Hitting rock bottom.

The absolute lowest possible point or level. The place a person in denial must reach before he finally is ready to admit that he has a problem and reaches out for help

....but hey, when you cant get any lower, the only way to go is up.

She was emotionally at Ground Zero. Britney hits Ground Zero, just days after she lost physical custody of her two boys.

Penn Zero: Part Time Hero 

An underrated cartoon on Disney that follows the adventures of Penn Zero, who unexpectedly inherits the job of his parents: being a Part-Time Hero. Penn must zap into various dimensions to take on the role of the hero in that world and save the day in their place. With the help of his friends, Boone, the Part-Time Wiseman, and Sashi, the Part-Time Sidekick, he must save the worlds from Rippen, a Part-Time Villain and Penn's art teacher, and his Part-Time Minion and principal of Penn's school, Larry.

Penn Zero: Part Time Hero is one of my favourite Disney cartoons

Edens Zero 

A really cool manga (and also recently became an anime) by Hiro Mashima about a boy name Shiki and his friends going on a journey through space to find the Goddess of the Sakura Cosmos, Mother. It's filled with fun, action and also a lot of dark and grim scenes.

Person 1: Hey have you read Edens Zero?

Person 2: No but I heard it just got an anime recently
Person 1: Yeah. It's pretty good. You should check it out.

coca cola zero sugar 

It's self explanatory. Coca cola with no sugar added. Do I need to say more?

Formerly known as Coke Zero, but apparently nobody knew what the fuck it was, so they had to lengthen the name for them damn millennials.

Coke Zero was a much cooler name than Coca Cola Zero Sugar
