The process one undertakes when taking a dump whilst on the toilet. The term has come increasingly into use with the advent of social networking sites that can result in some people spending hours, or even days, just dumping physical memory with little need to leave the room. If you try this it is recommended that you bring some water and some sandwiches with you to avoid thirst or starvation.
John: Who's in the toilet?! I've been waiting ages!
Jack: One sec...
Cindy: I'd give up John, he's on his laptop and crapping at the same time.
John: Ohhh, I understand now, I didn't know he was dumping physical memory.
EPIC rizz, centered around memorial day.
"yo, that dude pulls so many chicks!"

When someone is so insignificant, you erase all memory of them immediately.
Friend: "Who was that guy you were talking to?'
Me: "Who?"
Friend: "Oof, that guy got short-term memory zoned!"
