The Swedish Yo-yo is when somebody takes a hot load of spunk in their mouth and stands over another person. Then the person with the man mustard in their mouth starts to slowly drip the cum out of their mouth, then slurps it back up.
Alex: Dude, Amanda was doing the Swedish Yo-yo above me lastnite, and she didnt slurp it up in time so I got my own man jizz all over my face.
