"So, if you say (to a lady, perhaps), “I possess a deceptively large set of balls,” you could mean that your modest bulge belies the real heft of your testicles, which are actually so pendulous that you’re forced to strap them to your legs. However, you could also mean that you have tiny love eggs, and that your ball-shaped jean protrusions are actually caused by the hideous malformation of your wang. This is obviously something you want to avoid. If ever there was a case to be made for clarity of language, this is it."
