Hide the Cob
This is a game played by young and old guys all alike. You need about 5 or so naked dudes with huge boners standing around in a room and then another guy standing by the light switch. The dude standing by the light switch takes a corn on a cob and throws it into the air in the middle of those 5 naked dudes and turns the light off. The 5 dudes fight for the cob and whoever gets it takes it sticks it up their asshole. Dude at light turns light back on and the 5 dudes stand there naked and the guy who tossed the cob into the air has to guess which dude has it wedged up their ass.
Wow duder, after that game of hide the cob my asshole is sore.
