    [?My Eyes Glaze Over?, often ?Mine Eyes Glazeth (sic) Over?, attributed to
    the futurologist Herman Kahn] Also MEGO factor.

    1. n. A handwave intended to confuse the listener and hopefully induce
    agreement because the listener does not want to admit to not understanding
    what is going on. MEGO is usually directed at senior management by
    engineers and contains a high proportion of TLAs.

    2. excl. An appropriate response to MEGO tactics.

    3. Among non-hackers, often refers not to behavior that causes the eyes to
    glaze, but to the eye-glazing reaction itself, which may be triggered by
    the mere threat of excessive technical detail as effectively as by an
    actual excess of it.
