Used in any moment where one becomes speachless because somthing does not make sense.
When something does not make sense people refer to it as SneSne.
Comes frome the word the muddled version of the word sense, but mixed so that the word is in fact its meaning.
Originated from a typo.
Jenna- "I screamed when the grass started eating the cows."
Dan- "... SneSne.."
