Well that's something I've never seen before. Nothing like an unexpected gay moment to lighten the mood during a heated athletic competition. One second you're defending the bucket, the next there's a dude's ballsack tickling the back of your neck. Nothing you can do but laugh it off and give the other guy a nice, firm slap on that ass.
The confusion from the other players was hilarious, too. And good on the defender for being cool about it and playing along. I feel like some sexually-insecure guys would've felt threatened and slammed the guy to the ground, even though it was clearly unintentional.
