when you preform the act of ejaculating on your partners back. then sitting out in the sun till the substance dries and crisps. then have the partner eat "sun chips".
i busted a nut on my girls back by the pool and made her stay there till the jizz was crispy. afterwards she enjoyed my dna filled Colorado sun chips.
