well...martial art do helpla...
but let say if u open the door after u finish doing ur business in the public toilet..
then suddenly got some guy waiting for u and ready to get u... 
by the time u want to belasah them, they already belasah u. 
u know nowadays those pervert they have their own weapons... 
they also can spray u using horny perfume or sleepy spray or whatever they call it...
dun play-play...very dangerous...
cuz u know normally our public cleaner is  Indonesian or Bangladesh..
And even they look thin and small...it doesn't mean they are weak..
look at their muscle...they work harder than our malaysian people...
jeng je jeng...hahaha scary isn't it..

what do u mean taruh??
