Weapons in my room

I have weapons in my room
People who mess with me will be hurt
And if they continue to mess they will be in doom
And then thrown in dirt

I can easily do it all on myself
Would any1 notice?
How much pain Ive caused others
i shouldn't be around no longer

All my four weapons can be used on you
Or maybe all used on me
it all depends what you do
And what i may be

Mess with me and you die
Let me mess with you and you will survive
You make one step out of place
And you wont be alive

Now you have hurt me
I now need to use these weapons
On me and you
Let me do it!

I am now dead
Hope you are happy
I have no more pain
And i am proud
