Filipino Cage Fighter

So I started talking to a random Filipino guy in a bar and found out he was into MMA (Mixed Martial Arts) aka Cage Fighting.

I once dated a world champion kickboxer, and through her I had been exposed to the world of professional fighting.  To be honest when I see fighting on TV now it still gives me a boner…

The guy was big but softly spoken.  Like a teddy bear.  He was with a group of 4 girls and spoke of his one love who was living in Canada, soon to be reunited.  What a sweetheart.

I was intrigued about his sport and needed to know more.  So I asked:

"What is your base martial art?  Kickboxing, Jujitsu, Kung Fu, Karate?"

He responded calmly:

"Knife fighting"

What the?
