Masturbating for an extended period of time with a slow, fluid motion of the entire arm, while using syrup (typically maple) as lubricant in order to ensure the process remains slow throughout climax.

Tristan: Hey Jordan, tell Dyet that it's time for breakfast, I made pancakes

Jordan: I knocked on his door, he wont answer.

Tristan: The maple syrup is missing...
