Phenomenon created when some idiot with a loud car stereo believes the entire community would like to have their own music, conversations, or inner peace drowned out by the cacophony created by some angry black man shouting about bitches, a sampled bassline, and the sound of a car being vibrated apart.
Our day at the park was ruined by second-hand rap.
Basically it's those annoying times when you're in traffic or just in the car in general and the car next to you is listening to rap music very loudly. Quite annoying. Therefore, its secondhand rap.
We had to endure mass amounts of secondhand rap today while going to the mall.
