Acronym for "Never Gonna Stop Me", inspired by the Rob Zombie song "Never Gonna Stop". Used when a person gets incredibly drunk and/or continues to drink a ridiculous amount of alcohol at once. Also used to define the moments when this will likely occur.
Boy, did you see Brad yesterday? He really entered NGSM mode at the bars last night by the amount he was drinking.
