(n.) a new holiday that falls on National Best Friend Day each year, appropriately observed by licking your best friend to show your love and appreciation, possibly derived from the affectionate behavior of the dog, man's best friend. It is meant to be a prank that is both annoying yet endearing.

Bob: *lick*
Johnson: Y..you're my best friend too... :')
