Definition

An abbreviation of the French phrase 'je ne sais pas' (I don't know), adopted by texters too lazy to type full responses but fancy enough to use French. It's the digital shrug emoji in letter form. Bonus points for sounding vaguely sophisticated while admitting complete ignorance.

Example Usage

When my manager asked who authorized that expense, I just replied 'jnsp' and hoped it would go away.
