Acronym for “not a good look”. Used most frequently as a noun to describe anything unacceptable, foul, disastrous, inappropriate, or awkward. Originated in 2007 at Pace University in NYC; coined as a contraction of the full phrase after its repeated use of quoting a Pace staff member’s warning to students about returning to the dormitories intoxicated.
“The North Korea conflict is a NAGL.”
“I saw a waterbug crip walking down the hallway today. NAGL.”
