In efforts to get a tan by direct sun-exposure, one knowingly avoids high SPF values in order to get a darker skin-color ASAP. This usually means risking a sunburn. However, burnt skin will gradually turn tan.

Girl 2: That's OK, I'm power-tanning.

The state of being tanned to the point where you feel that your strength,virility and raw sexual potency have been drastically improved. A true power tan owner is out at every opportunity soaking up much needed rays and if the weather not permitting, is taking advantage of synthetic sources of sunlight.
