I understand your desire for a protest vote (one with humorous effect), though in order for any such naming jest to be reported in the media, that name must first be written-in, and in many states if someone has not filled the paperwork to be considered a write-in candidate, anyone who writes in that candidate will have their entire ballot (including down ballot) tossed out. I find it unlikely that anyone as filed the paperwork for "my left nut" to be a write-in candidate.
