When a male moves his lower abdomen, lower body in a way that causes his " nuts to lock up", or get tangled internally.
My husband was so busy being an asshole, by waving his legs at me while sitting in a lawn chair, that he maneuvered his "nuts lock up" from the rapid movement of his lower body; later requring surgery to be correcred..LMAO #KARMA
