the sense that is derived from the game "Call Of Duty Modern Warfare 2" that the sense when you hear a the click of the claymore and you try to run off or jump out of the way but you die. (Also applies in real life such as when you say something uncalled for or inappropriate for the situation and you want to take it back but you cant hence the claymore has already exploded).
Claymore Moment
a: I was going to get that camping piece of shit in the planes cockpit but as I turned the corner and heard the click and tried to go back but it was no use.
b: as I was trying to crack a joke to impress a girl i said a very sexist joke and I wanted to take it back but the claymore has already exploded as in she started to beat the shit out of me with her purse dildo.
A complete fail, yet riding it out until the end thinking you have done good. Being a dumbass and not knowing it. Being 100% sure of yourself, while everyone else knows you have fucked up beyond repair.
As I was telling everyone that they knew nothing about oil fields and letting them know I knew everything about oil fields, I had no idea everyone was thinking I was having a Miller Moment.
Wait..I was 100%wrong, even though I thought I was right...damn, Im having a Miller Moment!
