The term was started by the Youtube celebrities Ethan and Hila Klien while making a skit for their video, Hila's Biggest Regret (#askh3).
Hila-"Come on Ethan you've been in the bathroom for 20 minutes!"
Ethan-"I'm doing my good morning god bless Hila it's going to take at least another 10 minutes"
Ethan I need the bathroom! What are you doing?
Good morning God bless Hila!
What?
It's a good morning God bless Hila!
What are you doing?
*opens door*
What do you just open the door on people when they're taking shits? I'm doing a good morning God bless! I need another 20 minutes at least.
