What symbols indicate the option "does not matter"?

Question

User interface

Which icon (exactly the icon) is best to designate the choice option "does not matter", "does not matter", etc.? What do you associate this option with?
UPDATE:
Please do not answer "write in words". Imagine a situation where there is no other way.

Answer 1

with a guy, with a girl, a big company and "whatever"

in this context, just 3 dark figures are more suitable. As "with the company", only "faceless".

Answer 2

If I were you, I would make it possible to mark options through a checkbox. Selecting all options at the same time would mean "not important".

Answer 3

Write in words and don't make the user guess.

Answer 4

Depends on which icons are next to each other.
[ +1 ] or [ iGO ]

Answer 5

N/A ?

Answer 6

Equals sign = (It doesn't matter.) And write it in the letter "omega". Well, other puzzles can be invented so that the user suffers
