When one person is on the toilet for a at least 8 minutes, taking a crap, calls another on their phone from the toilet.

Unlike when someone butt-dials you or drunk-dials you, DUMP DIALS mostly occur sober, and on purpose.
"Hey bro, sorry to DUMP DIAL you, but i had to call you from the can...I'm getting a blumpkin!!!!"
