Someone with homosexual sympathetic tendencies, who believes his testicles are larger than average. This person likely has undiagnosed developmental delays and can't fathom their testicles have retreated back inside their scrotum. In serious cases the entire scrotum will retreat, leaving the appearance of a vagina where the testicles used to reside.

Used to describe (generally female) imagery that's suggestive, but in a PG-13 sense rather than an R or above sense.
