A cursory Gsearch seems to indicate this means to act strangely as if on drugs.



So, your "cursory Gsearch" didn't indicate anything. You stumbled across one of the many Urban Dictionary entries that has a statistically insignificant number of votes.

FWIW, I heard parts of an interview with guy who runs Urban Dictionary on NPR this week. He has a full-time job at Google. He's not really a logophile, he's more in it to play with the community website interaction / programming aspects of collecting, accessing, displaying such a large dataset.
