This sign looks just like you are licking an ice-cream cone twice.
Note: You don't actually stick out your tongue in a true-to-life licking movement. If you do, that would inflect the sign to mean something to the effect of "She took two big licks."
Rather, you do the sign in one of three ways: 1) Use two very, very slight licking movements with the tongue, 2) don't use any mouth movement, or, the version I see most often used, 3) slightly mouth the words ice-cream. I've seen it done all three ways and by native signers. I do it here with no mouth movement. I just asked my wife how she signs it and she slightly mouthed "ice cream." I showed her the version with two small licks and she didn't like that version at all, but she thought the no-mouth-movement version was "okay." If you see it a certain way in your area...feel free to vote.
