Scrawny Kung Fu Grip 

The act of shoving a baby hand in a gay man rectum, whilst the hand contracts making the aforementioned grip. This term is most widely used amongst pedophiles.

Call 911, I think I saw our neighbor with our baby! I believe they are attempting a Scrawny Kung Fu Grip.

i know karate, i know kung fu, you mess with me, i mess with you!

I think I'm cool and I totally pwn you so don't mess with me!

One might say "i know karate, i know kung fu, you mess with me, i mess with you!" To ward off unwanted attention from bullies. Mostly unsessful.
Also, a phrase used often by geeks trying to sound cool.

“Sure, Baby, My Kung Fu Is Best.”

The complete package of alpha dog. Anytime someone asks you if you can do something hard—hit them up with this punch-line. Your peers will know what the fuck is up.

Stephanie: “Hey, Jordan you big Jew-nosed, egorgian bitch, can you even bench 100 pounds.”

Jordan: “Urghhh. I don’t know.”

Stephanie: “What about you, Dalton?”

Dalton: “Sure, Baby, My Kung Fu Is Best.”

Dalton proceeds to bench 300 pounds since those with kung fu that is best can do such acts

Heavy Kung Fu 

Really good and disgustingly badass. A mixture of heavy, meaning really good or deep and as kickass as kung fu.

Guy 2 "Because I'm Heavy Kung Fu"
