For flaky, we must throw out the much too tame traditional dictionary, and go to the Urban Dictionary, which nails it many times over:
An unreliable person. [See 'Obama' who hasn't improved one economic measure for black people, let alone anyone else, except for their government dependency]
A procrastinator. [See 'Obama' who dithered and dithered for three days after the Fruit of Kaboom bomber incident in route to Detroit because he and his administration were all on vacation, again. And how many months did it take him to decide to surge in Afghanistan?]
A careless or lazy person. [See 'Obama' who was content to let the House and the Senate duke it out over their versions of healthcare reform and provided no legislation of his own, or who let BP clean up the spill in the Gulf despite a long-standing contingency plan put in place by the government in the wake of the Exxon Valdez spill in Alaska]
Dishonest and doesn't keep to their word. [As in 'Obama' who didn't close Gitmo and didn't try the terrorists in civil court]
They'll tell you they're going to do one thing, and never do it. [See 'Obama' who promised to end the war in Iraq but our soldiers continue to die there]
They'll tell you that they'll meet you somewhere, and show up an hour late or don't show up at all. [As in 'Obama' who, the president of all the people, deliberately misses church, and patriotic or Christian holidays but never seems to miss a Muslim one]
Also spelled "flakey", or "flake" in the noun form. [Also spelled 'baked' in the adjectival form, as in the noun 'head']
She told me she would send me her pictures, but it's been 3 months and she hasn't sent me shit. She's flaky as hell.
