The act of defecating off a cliff or any tall object. Safety note: Always base dump with a partner and never base dump into the wind with flu like symptoms.
Steve asked Fred to hold his wrists while he attempted his first base dump off the roof of his dorm.
Tim was disappointed and a little dirty when his base dump got stuck on his windowsill.
Taking a dump while having a virus/bug. When you complete your dump you will feel refreshed and know the worst of it has gone by. This dump tells you that you have flushed away the last bits of your virus and you may now get back to living your life. This dump will often be runny, a queer colour and/or smelll terrible. When completion of dump takes place, one must stand, lift arms above ones head and do a victory march around the house. Flushing of the dump is not necessary straight away incase you want to show friends/family what you have accomplished.
Friend: Aw WTF?
You: Yeah, I know, pretty impressive huh?
Friend: You have somethingwrong with you
You: It was one of my better victory dumps I'll admit
