Wtf is this hole/orifice? Cold AC coming out

What is the hole in the pics below? It's coming out of the passenger side firewall in the engine bay right below the dryer. It had cold air blowing out of it when i had the ac on full blast. Should it be plugged or does it run somewhere?

Yup its supposed to be there!! It's a drain which sometimes becomes clogged and needs to be cleaned out.

I get water on the passenger side floor so I thought mine was clogged.. That's usually an indicator of a clogged drain hose.
