Did I coin this slogan? According to Google, I did: this is one of many (MANY!) turns of phrase that the internet has no record of before I said it… although it seems as if it should be in common usage (frankly, it seems as if you might find it printed on a t-shirt!).
Whenever I search for this kind of thing, I'm wondering, "Did somebody say that in a movie I saw as a child… ?" --i.e., I'm wondering if I really made it up myself, or if there's some familiar source for it that escapes me.
