Incestuous Lube

Listen up, you dense mammal. You probably think lubricant is just for your car, but it's important for other stuff, too. The joke is about incest, which is when family members do the horizontal tango. They should use lube because, you know, it can be uncomfortable otherwise. "Slow down and apply more lube bro" is a phrase said during sex that gets a whole other meaning in the context of incest. It's supposed to be shocking because it makes a very uncomfortable subject seem casual. Get it? Maybe not.
