Famous quotes containing the word buttocks:

    and in moonlight she comes in her nudity,
    flashing breasts made of milk-water,
    flashing buttocks made of unkillable lust,
    and at night when you enter her
    you shine like a neon soprano.
    Anne Sexton (1928–1974)

    They have thrown away her electric toothbrush, someone else slips
    The key into the lock of her safety-deposit box
    At the Crocker-Anglo Bank; her seat at the cricket matches
    Is warmed by buttocks less delectable than hers.
    Randall Jarrell (1914–1965)

    If your buttocks burn, you know you have done wrong.
    White South African proverb.
