A guy from America asked the gal from Sweden to dance at the college fraternity party. While they were dancing, he gives her a little squeeze, and says, "In America, we call that a hug". She replies, "Yaah, in Sweden, we call it a hug too."
A little later, he gives her a peck on the cheek, and says, "In America, we call that a kiss". She replies, "Yaah, in Sveden, we call it a kiss too."
Towards the end of the night, and a whole lot of drinks later, he takes her out on the campus lawn, and proceeds to have sex with her. While he's pumping away he leans over and says, "In America, we call this a grass sandwich".
She says, "Yaah in Sveden, we call it a grass sandwich too. Only we usually put more meat in it."
