from urban dictionary.. ham sandwich 16 up, 25 down When you approach a sleeping person, and gently lower your buttocks over their nasal cavity, sealing off air flow. When they open their mouth, gasping for air, strategically lower your *beep* into their mouth. Upon restriction of breathing, they will regurgitate the *beep*. You have successfully performed a ham sandwich. My name is John Ward Doucette from Sault Ste. Marie and I always pretend to fall asleep so I can get a ham sandwich from my closest buddies. lol...
