A slang term for MSNBC. Similar to the Moonies from the early 70's prone to brainwashing due to their fragile hippy brains being left mushy after taking LSD. So is the MSNBC viewer drunk on left wing propaganda, hellbent on riding the Obama/Progressive boat straight to the bottom.
Example: Did you see how angry Moonbeam got when I mentioned how the Koch brothers and Warren Buffet are cut out of the same douche cloth? She must still be trippin on MSLSD.
