Top definition
a unit of measurement for length/distance that is impossible to see to the naked eye. Most scientist estimate that 4,963 bohldacks = 1 inch, but the real length of the bohldack is still under question. The term was originally used to describe the size of Bohland's penis hence the bohl portion of the word.
Tom: Hey Joe, how big is your penis?
Joe: I would say average. You know about 35,000 Bohldacks(roughly 7 inches).
