The phrase Karen is referencing comes from 255c of Plato's Phaedrus:
And when this feeling continues and he is nearer to him and embraces him, in gymnastic exercises and at other times of meeting, then the fountain of that stream, which Zeus when he was in love with Ganymede named Desire, overflows upon the lover, and some enters into his soul, and some when he is filled flows out again; and as a breeze or an echo rebounds from the smooth rocks and returns whence it came, so does the stream of beauty, passing through the eyes which are the windows of the soul, come back to the beautiful one; there arriving and quickening the passages of the wings, watering them and inclining them to grow, and filling the soul of the beloved also with love.
