ON IT! 

To be on that ice (meth)!

YOu turn on that torch lighter and put it to your straight shooter, once the tip of the straight shooter is hot, you hover it over that line of ice and short all that goodness into your nose up through your brain and into your lungs where then you blow out that thick cloud of greay and white smoke and look over to your friend and say "GOD DAMMIT IM ON IT!"

on it like a car bonnet 

To be all over something, having it under control.

Some say it is derived from Essex girls famed love of sex on a car bonnet, others from the female models at car trade shows that lay on car bonnets. (NB: UK Car Bonnet = US Car Hood)

To be "On it like a car bonnet" means you are literally all over something, like an (Essex) girl on a car bonnet"

"Are you looking at this problem?"

"Yeah, I'm on it like a car bonnet"

On it like blue bonnet 

I'll all over it.

You're already started on a favor someone asks of you. Then they ask you if you've started and you say, "I'm on it like blue bonnet"
