Short for "Do the
Math."
DTM is when you play Sherlock Holmes with your brain after a wild night out. It's all about crunching the numbers and figuring out how many freaking beers you chugged down the night before. It involves mentally retracing the steps of the evening, meticulously calculating the number of beers consumed, and, oftentimes, experiencing a moment of self-realization or mild regret. DTMing is commonly practiced as a means to evaluate one's
alcohol intake, gauge the level of intoxication reached, and to potentially understand the subsequent effects on both memory and physical
well-being.
