Some distinct themes here. For instance, finding other cities to look down on ("At least we're not Flint, Cleveland, Cincinnati"), talking tough ("I'm a Detroiter ... bitches," "Where we chew up our kids before we spit them out," "We have packs of wild dogs, do you?" "Stick 'em up," "Enter at your own risk"), snappy lines ("I'm diggin' Detroit," "It starts with the D," "Motown has heart"), historical allusions ("Aloha, motherfuckers," as famously said by former Mayor Coleman Young; "Say nice things about Detroit," as businesswoman Emily Gail implored her fellow Detroiters; and variations on the post-1805 slogan "We will rise from the ashes") and sheer desperation ("Flatlined," "Sucks, but in a cool way," "Detroit: When you can't go anywhere but up"). Then there were the references to comeback, put best by the suggestion above, depicting the city as a sort of perpetual motion machine of decline and regeneration.
