Not sure what heli-bungee exactly is? Well, you're not alone.

Even Will Smith had no clue when he was issued the challenge by the YouTube group "Yes Theory."

The group is all about "seeking discomfort" and "challenging what society considers normal." Basically, they face fears and search for new experiences and challenges to say "Yes" to.

They decided to challenge a "positive and motivational role model" who's inspired "millions," including them: Will Smith.

The actor did some extensive research, meaning he strung his "Men in Black" action figure to a drone, before accepting the scary task.

Will has three conditions: it had to be done for charity, done after he finishes filming "Gemini Man" in Savannah, Georgia, and had to be done over the Grand Canyon.

So, sometime in the near future Will Smith is going to bungee jump from a helicopter over Arizona's most-prized natural wonder.

Maybe even with Tom Cruise at the controls?
