Top definition
a term coined when a psychologist told my father that I, his son, was a genius. To properly express his disbelief in my mental capability and, simultaneously degrade my self esteem he created this word. It should be used accordingly.
shrink: the tests are in, your son seems to be very intelligent. in fact, we believe, he is what you would describe as a genius

dad: That boy aren't no darn genius! he might be a gennieass but he aren't no genius.
