"That grilled cheese was Awesome."

Grilled cheese describes lack of hygeine in a woman's private area. The woman's hairy vagina has been used too much so there is semen residue in her pubes and when she opens her legs it pulls apart slowly like a grilled cheese sandwich. Just like pulling apart the bread slowly and seeing the melted cheese.
