When your nuts to slam down which stretches out your sack and causes a rubber band action as it tightens back up and slingshots your nuts into your pelvis.
I get Nut whiplash when I air 2 flat on the ice coast.

What does nut whiplash feel like?

After you drydock, it sometimes feels like the larger nut bounces off stuff and flings into your bunghole.
