The (usually sarcastic) celebration of the philistine ideals of low-brow, materialistic culture over the "highly overrated' ideals of an intellectually curious, artistically creative one.
My knuckledragger boyfriend is so perfect for me. I especially love his philistine-tastic pea brain. It's his second best feature.
I'm going to leave my boss a philipperdecker for not giving me a raise. Too bad I will not get to see his face when he sees my shit trying to flush his toilet.
