H2D - Holla to Dat means you see something so wild, you can’t help

Holla to Dat means you see something so wild, you can’t help but yell at it. Only the coolest people use this term.

I saw a guy eat a whole pizza in one bite. I yelled, 'Holla to Dat!'

My friend did a backflip off a chair. I was like, 'Holla to Dat!'

That dog just ran through a pool. I screamed, 'Holla to Dat!'
