The 'heisman' is a sex move where the man is standing up and the woman is on her back (preferably at hip height for execution), you then put one of her legs in your arm as you would carry a football (without cutting off circulation and holding her leg under the knee) - other arm will be your stiff-arm - and proceed with perfect 'heisman' form getting one leg up in a ready position (same leg as stiff-arm)----> Most importantly stiff-arming her LOWER stomach with decent pressure for maximum performance, you WILL...when properly executed...score a touchdown you will never forget.
"I gave this chick The 'heisman' last night and she was screaming 'TOUCHDOWN' all night...I finally feel like a professional athlete."
