dunno.

Answer to everything, explanation for nothing. 
Not yes, not no — just orbiting in the middle.
A shrug dressed as a word, the ultimate get-out-of-jail-free card for questions you never wanted to answer.
Wear it when decisions feel overrated, when clarity is optional, when “whatever” speaks louder than certainty.
dunno. 
Uncertain. Unbothered. Universally understood.
