To rattle one's salad: (v.) To make a show of eating healthy foods; to gloat about one's 'proper' diet; to display a kind of smug satisfaction about one's food choices, as in "I know I'm getting kind of tedious about this health thing - I catch myself bragging about how much I ran on the treadmill and I rattle my salad in front of those guys every single day."
