it means inner and is also known as weed that is grown indside. - endo when refferred to dank weed doesn't come from the word "indoor", thats a stupid supposition. it comes from the word inner because its grown on the inner part of a house. number 3 answer, your an idiot, hopefully you will be the number 4 answer now. in no way is your answer correct. everyone on urban dictionary is now dumber because of your definition, may god have mercy on your soul.
