The name of a devastating claymore in the Call of Duty games. These usually are placed in random spots yet result in a double or sometimes even a triple kill. Often players will abuse the scavenger perk to plant multiple dadmores. This results in team victory nearly 100% of the time, and it will make the other team scream and complain after the game. When the other team starts talking, just keep replying "I'm better" until they stop talking or leave the game.
John: "Oh no... i think there are multiple tangos behind us!"
Adam: "It's alright, I murked those scrub sauces with a dadmore while they were trying to flank. I can't wait to tell them that I'm better!"
