I am also interested in this expression. Google searching turns up nothing, except maybe a reference to marijuana.

So maybe 'broccoli' is their way of saying craziness? Like being on Google drugs. But obviously that's not a perfect fit. Maybe its a misspelling of something else?

No one in Google uses this as an expression. It's close to something people actually do reference, but it's not described like this.
