1. A forceful rush or flow forward.
   • 1856, Elizabeth Barrett Browning, Aurora Leigh‎, New York: C.S. Francis & Co., published 1857, First Book, pp. 32-33:

     The love within us and the love without
     Are mixed, confounded; if we are loved or love,
     We scarce distinguish. So, with other power.
     Being acted on and acting seem the same:
     In that first onrush of life’s chariot-wheels,
     We know not if the forests move or we.

But it was only a momentary check, like the tense silence between blasts of thunder. The second onrush was greater than the first. It swallowed up the two men.
