A short black person, especially one who is a dwarf or midget. It is derived from the term "coon" used to describe african-americans and the term " leperchaun".
A pena. The origins are unknown. It resides in caves and occasionally under the beds of unsuspecting children. Normally it feeds on maple syrup because most live in Canadian territories; however, it loves to eat the skin of lepers. Scientists are not sure, but it is possible that these creatures are part turtle, part llama, and part chicken fetus.
I was tucking my son into bed one night, and he told me that there was a Lepercan underneath his bed. We disposed of it quickly with our family Kalashnikov.
(n.)- a magical contraceptive device that prevents the spread of leprechaunism. Also, a prophylactic of the wee, or stature-challenged. See also femi-leprecondom, the female version.
Thank Jesus Gaelen wore his leprecondom when we did it last night beneath the Blarney Stone; I don't want to be carrying his homunculus for 9 months.
