ravenning 

erratic, unpredictable and threatening - possibly motivated by uncontrolled primeval instincts - rage, hunger, lust or even madness

(You have to make the verb up first to develop the adjective. I started using it as a gerund to describe my new puppy's behaviour to friends. It is marvellously onomatopoeic as nobody seemed to have any trouble understanding it as an assumed existing word.)

the dog was a ravenning monster

ranning 

The act of running with little clothing in order to get a good tan. Ranning allows for both good muscle tone and good skin tone.

M: Wow, you look so tan! Have you been spending a lot of time at the beach?
B: Nope, I went ranning yesterday for two hours without my shirt on and now I'm buff and tan!
M: I'll have to try that! I hate wasting time laying on the beach.

Kylo Renning 

To Kylo Ren someone:
When giving a blowjob, the giver reaches up in a Kylo Ren motion to choke the receiver as they continue to give a blowjob to climax. The giver must have long arms to achieve this incredible feat.

Did you hear that Taylor was kylo renning Xander last weekend? He said it was the most intense sensation he’s ever had.

Ravening

The process of sticking one's hand, in the shape of a bird's mouth, into a man's ass and proceeding to dig into his ass. If done correctly, the man will be stunned and completely immobile for at least five seconds. Does not work on women.

He ravened you!? Yes, he was walking around ravening everyone!!
