look up any word, like bukkake:
 
1.
The act of eating a lot of snacks and convincing yourself that the process of eating those snacks qualifies as a physical activity. Therefore you are "exercising" and snacking all at once.
Example One:
Mom: You're so lazy, get up! Get a job! Take a walk! You do nothing all day long!
Son: Mom, i would do all those things, but that would interfere with my very strict snackcercising schedule.

Example Two:
Jenny: Want to go to the gym after school.
Alice: Nah, I'd rather just snackcercise for a while and call it a day.
