Mcferrinism is a religion/lifestyle based on Bobby Mcferrin, who wrote the song "Don't worry be happy", which is the main principle of Mcferrinism.
Mcferrinism is not like other religions in the way that Mcferrinists don't believe in a god, but rather try to stay happy and cheerful as much as possible. It is important to note that Mcferrinism does not forbid being angry or sad etc. but rather tries to promote a wave of joy and happiness:D
-I know, he must be a Mcferrinist.
-Dude, Don't worry be happy
Cause when you worry
Your face will frown
And that will bring everybody down
So don't worry, be happy.
- Wow, thanks, i feel so much better now, i think i'll convert to Mcferrinism.
