A play on the original acronym HAM, but to a more extreme effect..
1) To go HAM (hard as a motherfuc*er) so nasty, you are reminiscent of Darvin Ham's monster dunks.
2) Slam 'dunking' anything. Implication of goin-in hard.

2 - "How'd things go with that girl last night? Did you go-in
"Let's put it this way.. we were goin Darvin Ham all over the place. Broke her coffee table, faucet, bed frame, and apartment elevator! It was out of control
* may also be used with a project proposal at work, awkward serving of divorce papers, etc.
