To speak in hyperbole, but not just any hyperbole. It is to repeat whatever anyone says in several larger words, generaly with a superfluos word of the day thrown in. It is used to make one sound smarter than they really are, but it only accomplishes making said person look like a huge fag.
There is this kid in my history class that always answers the teachers questions Luckay Style. I hear he has a huge dong.
