Grumble junkies are mostly conservative-leaning posters complaining about the President (and any one remotely associated with him in any way), though experts theorize that should a conservative get elected President, liberals will rapidly take to the fore of this peculiar subcuture.

Real Concerned Citizen: "Impeach Obummer, Biden, Holder, Reid, and Kerry NOW! The government is conspiring to take YOUR (insert amendment here) rights!"
(scramble names, repeat 10x daily)

Reply: "Man, you are such a grumble junkie."
