The time most frequently associated with using the bathroom, specifically a poop. With school ending at 3:00pm, and after school sports beginning at 3:30, 3:20 becomes the perfect balance between dressing out and doing your business with just enough time to make It to practice. Similar to 4:20, the phrase was coined after a group of friends realized that everyday before track practice, they all took a poop at the similar time of 3:20.
Chris: Hey, Logan. Ready for track practice this afternoon?

Logan: Hell yea! I have been holding in this monster shit all day though man. I'm gonna have to stop and make a quick 3:20 poop time before practice.

Chris: I feel ya man. I will cya there!
