the act of licking another person's eyeball with one's tongue]; blatany derives from the Latin "blattire" meaning "to lick seeing-organ."
The word entered regular English usage through a bad Full Metal Alchemist] anime dub in which the name of the character Gluttony] was translated as Blatany. The modern definition is thought to have arisen from association with the character's distinguishing tongue and unholy hunger.
Blatany is the sweetest sin], baby. Hold still while I run my tip across your--OH MY GOD THIS IS THE MOST AWKWARD FEELING IN THE WORLD! Why would anyone lick anyone else's eyeball!?
Leviticus 18:36-38 - Thou shalt not blatanize with mankind, as with womankind: it is abomination.

Let me tell you Bro, it's not gonna help your chances of impressing her. Not one bit.
