The act of licking from the butthole, through the gooch area, all the way to the clit (or balls) in one fell swoop.
"I saw you leave the party with that chick, how did it go?"
"Bro, I gave her the juiciest Elk Lick ever."
or
"Dude, what's wrong?"
"I was just with my girlfriend, and she hit me with an Elk Lick when I wasn't expecting it."
A naked woman gets on her hands and knees. Naked guy #1 kneels in front of her, receiving fellatio. Naked guy #2 kneels behind her, performing anal intercourse. Meanwhile, guys #1 & #2 proceed to play cards ( blackjack, usually) on the womans back, being sure to throw down the cards vigorously at the end of each hand.
Yo, last night we were in an Elk Situation with this chick, and she kept complaining that we were hurting her back with the cards!!
