Get the Car Bonnet mug.
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"

two police officers in discussion, after one of their fellow officers go off on a foot chase:

officer a): where's my partner Michael?, you seen him?

officer b): i think I saw him on it like a car bonnet, chasing after that hot female teenage delinquent.. (moments later): Tom, here goes the answer to your question, there's Michael, on it like a car bonnet; i don't think we should be disturb him (pointing at a car parked some distance away). He is on it like a bonnet, raping that girl, instead of giving her a hefty fine. I hope they become a cute little couple, lol.

officer a) Thanks man, well looks like that girl didn't have the money to pay the fine anyways, so she got what she deserved. Let's just hope she doesn't have a beautiful disaster. Hang on partner, let me call me my wifey, tell her aqbout Michael and his big fish.

officer b): don't call your wife with such nonsense, you buckwheat brains; she may be on it like a car bonnet, probably playing bingo with her girlfriends or whatever.

either

a) for a police officer/detective/Sherlock Holmes or anyone along those lines in hot pursuit of either a of a criminal (usually a juvenile delinquent truating or in search of new adventure (unplanned) in the great outdoor wilderness.

b) can also be used as a derogatory term for a couple who have sex outside in public (usually on the bonnet or hood of their own parked car).

NB: my definition a) comes from the fact that some criminals aressted after a foot chase are brought back to the officer's patrol car/van, physically shoved onto the hood and then handcuffed. Also when people get lost in the wilderness while travelling by car, they might sit on the hood/bonnet of their car and think about what to do, sometimes waiting just long enough for an unplanned adventure to come and find them 9like a bear coming out of the wilderness to smell your vehicle). my definition b) refers to the fact that some couples do use the hood/bonnet of their car to have sex in public, think its okay, simply because its their car.
