Here's how it works:
1. Pig Latin: In pig latin, you move the first letter of a word to the end and add "ay".
2. Backwards: To say "snarky" in pig latin, you would get "narkysay".
3. Reverse: "Icksnay" is just "narkysay" spelled backward.
So, "icksnay" is a playful and slightly irreverent way to say "snarky" in pig latin.
