take this, for instance.
A dewey Decimal rap is dorky enough, but good god, get the lexicon right. "What's der word"? Where are you from, Wisconsin*? Even my mom would know it's "da word". And has anyone under 30 said "get down" or "bust loose" non-ironically in the last two decades? Egad.
Nothing like a middle-aged white lady trying to get through to "the kids" to provide you with a spine-rattling cringe.
*She's apparently Australian. That's no excuse for rapping like a midwestern farmwife circa 1886
