What is Ynbc?
1.
Generally stands for "yeah nobody cares." It is often found following statements of which no one on the face of the planet would care about or excessive e-peen. For those not into the whole brevity thing, "yeahnobodycares" may also be used. Capitalization doesn't really matter (i.e. ynbc, Ynbc, YNBC, yeahnobodycares, YeahNobodyCares).
