fat-ercise
When a highly motivated fat person pursues physical fitness. Does not necessarily indicate a desire to lose weight, or a lack of aptitude in fitness activities. This activity has been known to shock innocent bystanders and stun haters into silence.
You can call it fat-ercise, but I call it lapping everybody on the couch.
That chubby chaser better get his running shoes on, because this BBW gets a lot of fat-ercise.
