Although a freindly parting salutation, this has it's roots planted firmly from the 70's pop culture of under-aged, underground consumption of marijuana and alchohol. This basically means: I have been talking for the last 5 minutes, and now realize that you are not only high, but not capable of understanding simple conversation, which, at this point, we can have at a later time, when you are not in such a state.
