When a male shaves his testicles and afterwards neglects to shave them for an extended amount of time resulting in hair growth that becomes prickly (much like a miniature bulbous cactus) and pokes the testicles or inner thighs constantly in a painful manner.
"Bruce thought he was going to have intercourse last weekend and shaved his testicles on Friday before going out for the evening. It's now Thursday and he told me that he hasn't shaved his nuts since last Friday, he must have a seriously irritated ball sactus."
