A small rodent not to be confused with a mouse. They are very fuzzy and friendly. They also like to dance. Also, they will run in little plastic or metal wheels until they die from either heart attack or exhaustion. Make good pets except they are known to plan world domination, escape artists and also like to run around your house and poop everywhere.

(verb): To walk on a health club's treadmill for a prolonged period in an attempt at losing weight. Less commonly it can refer to running on the treadmill or using an elliptical trainer. In most instances, a treadmill workout qualifies as hamstering if done at such a leisurely pace that one is unlikely to lose much weight or derive significant cardiovascular benefits.
Now that summer's approaching, your typical cardio bunny will hamster away in the gym, in the hope that she'll look good at the beach.
