Physical Weak Points?

Question

Ok, i have this ''friend'' and ( ok, hes a d!ck head ) he always does extremely weak punches to my stomach, and they absolutely hurt like hell, and hes told me its the diaphram or somewhere inside the ribs.

So, this is basically 2 questions:

1. Is there any other extremely weak points ( except dwn below ) that a small tap could make hurt, and NOT a pressure point, somewhere that involves tapping/punching them

2. How can i stop it hurting when he hits me?

ANY advice will help.
Thanks

And let me add he's not tickleish =)

Answer 1

The key physical tender or sensitive points are remembered by the accronym SING

S= solar plexus
I= instep
N= Neck and Nose
G= groin

An effective hit in those will slow most people down. The area you have described being around the diaphragm and ribs is the solar plexus

Answer 2

yes i didint know very much weak points but i know these: neck, your back, eyes, the temple, ribs , tibia, at the top of your knee (about 3cm going up the knee) , foot, face.
tell your fiend to stop, tell him your going to call the police (joking and if he becomes agressive call them),
beat him, yoke him (like your going to beat him up with at least 3 friends.

Answer 3

punch him in his kidneys, That hurts like hell
or karate chop him where his shoulders meets his neck, do it hard enough it will knock him out for a few seconds ( people have been known to pee themselves when this is done correctly )

Answer 4

Yeah...head and baseball bat!

Answer 5

tickle...
