A Dump Invalidation or a DI is when you are taking a dump and its so hard and dry that halfway through the painful process, you decide to suck the dump back up your butthole, eat some fruit, try again later, and hope for the best.
Person 1: man i just had to DI. it hurt like 712904 needles entering my butthole.

Person 2: HAHA. better luck next time.
