Similar to the Hulk smash, when a guy orders pizza hut dunkers and dips his hard penis in the chocolate dipping sauce. After the dunk is complete, you stand up and scream "DUNKER SMASH!!" and you proceed with hitting the girl across the face creating a chocolatey mark on the face.
"Last night soccer phenom Zach Dunker Smashed the shit out of me, I will never eat at Pizza Hut again"
