Potleg
1. The repercussions of a swift knee to the thigh area, resulting in bruising of said area for the recipient and much lulz for the one who supplied it and any bystanders. The potleg itself may also be delivered via the medium of the heel (of the foot), elbow, knuckle or household object. In extreme cases, a potleg can leave the victim unable to walk properly for quite some time and may induce nausea.
