Like it, or wipe it?

Don't F.uck with me
I am the power
If you didn't hear me
I`ll shout louder
I been in hell before
And now I'm an addict
I plant a C4
and that's when you call the medics.

I never gave a f.uck about what you said
You'll walk on these street, one minute and you'dead
I told you twice but ya ain't puttin' it in your had
A bullet hits you and you all gone mad.
Your lying on your bed, holdin' Ur head

This needs a lot of work ...
Try using wordplay, multi's and punches.

explain

Use some wordplay to show off your skills. For example: Your xss forgot, just in case you don't remember me, I'll run your brain around the block, to jog your fxcking memory (Eminem). Get it ? Run around the block, jog your memory ...

Multi's are just multi syllable rhymes. I'll give you an example and show you one of my lines:
No chance son, u think u strong minded but u can't pass me even if u push me
Like a tampon, you're long-winded, nasty and your origin is pxssy
As you can see, all the bold words rhyme and not only the end of the sentence.

Last thing is punches, better known as punchlines. Every rap needs some just to make it funny to read. For example:
"Im far from broke, got enough bread and mad ho's, ask Beavis i get nuthin but head" (Big L.)
Beavis, Butthead, get it ? This could be considered as wordplay too, but you get the point I guess.
