A brown turtle is conducted much like a secret Santa. Except one gift is replaced with a log of shit. Everyone opens a gift in a Yankee swap fashion and whoever opens the log of shit (brown turtled) loses that years swap. Thus having to be deemed the brown turtle until the following Christmas.

Group: "FRAN GOT BROWN TURTLED!!"

a turtle licker is a person who licks the end of a poo when it is just coming out of someone's bum.
these people get a good rush of adrenaline when doing this and think its a brilliant sensation.
