Scholars once thought that "Cubby" was an ancient man-beast, a result of years of human/cow/octopus inbreeding. Recent discoveries have laid such theories to rest, however. It is now known that Cubby is a singularity of gayness. There is such a high density of gayness in one Cubby, that it collapses on itself and becomes a gay black hole, or a "Cubby" hole. It is often used as slang for gay people that are so gay, the observer of the Cubby feels immediately inclined to stuff penis after penis into their mouth.
Ugh! That guy is SO gay! He's a friggin Cubby...I mean seriously, let's go have sex with some gay men. Over and over.
