Former UFC flyweight king Demetrious “Mighty Mouse” Johnson recently gave two Streetbeefs competitors – Death Sentence and Winged C – a taste of just how steep the gap can be between amateur fighters and elite professionals.
Filming for his YouTube channel, Johnson spent time training and sparring with the duo, offering them mentorship from one of the most accomplished fighters in MMA history.
But during a sparring round with Winged C, things took a sharp turn.
Johnson began to feel disrespected when his partner repeatedly said “good boy” mid-session – a choice of words that struck a nerve.
Here is what Johnson had to say about what happened:
He kept saying good boy – Does he realize I’m f*cking 38 years old and have done this for 20 f*cking years?
I was about to go to a little f*cking dark place…
They’re always clip farming. It just f*cking pissed me off.
That frustration boiled over when Johnson landed a head kick that dropped Winged C.
It was a rare flash of temper from a fighter known for his composure, but Johnson admitted he felt the moment called for it:
This isn’t a proud moment.
I get nothing out of [it]…But I felt it was necessary to do that.
And, yeah, hopefully they f*cking learned from that.
