The Earnhardt is a sexual tactic that involves the tight rolling-up of a Dale Earnhardt souvenier T-Shirt, inserting one end into a woman's vagina and the other into her rectum, in equal proportions. Once completely inserted at both ends, so that only a fraction of shirt is showing from vagina to anus, the exposed fabric is pinched and held tightly. The woman is then instructed to lay flat on the carpet, legs wide open and pull herself forward. As she does this, she slowly removes the shirt from within her as it is being firmly held and eventually brings herself to climax.
A derivative of this is "The Angry Earnhardt" where after removal, the other party proceeds to whip the woman's back with the vaginal secretion and fecal matter soaked t-shirt.
