The NG button emoji is a seldom-used emoji because no one knows what to use it for. This symbol is mostly used to indicate that something is no good to help avoid a negative situation.
NOTE: NG Button was accepted in 2010 as part of Unicode 6.0 under the name “Squared NG” and labeled Emoji 1.0 in 2015.
