Justin "baby" Bieber has created a new trend, Glass Butting. It's a simple new step where you walk into a glass door believing it will just open.... then slam dunk.... right into the glass while still your in motion and the glass door refuses to open.
To the normal human being this may cause some damage, though those without a brain it's a blast!
Some will cover up the somewhat idiodic trend by stating the Glass Butt trend was just an accident, no fault of Bieber, they'll claim "he walked right into the door after after the door's failed to open" thinking it was going to part for him like the Red Sea...
Bieber isn't having the greatest run with his head lately.
His Glass Butting trend could be the blame for his brainless mishap when visiting New Zealand when he failed to correctly identify German...which he claims was due to misunderstanding the New Zealand accent, (where they say Gurmin, hey bro).
Sorry, Baby Bieber may need to seek a Brain Surgeon and maybe an optometrist for some frames!
