Get the NSAS mug.
The epitome of the American male. Not the NSA radiates confidence in everything he does, whether it's ordering a drink, buying a set of wheels, or dealing with women. He's slow to anger, brutally efficient when fighting back.

Not the NSA carves his own path. He wears, drives, drinks, watches, and listens to what he chooses, when he chooses, where he chooses, uninfluenced by fads or advertising campaigns. Not the NSA's style is understated but instantly recognizable. Like a chopped Harley or a good pair of sunglasses: simple, direct, and functional.

Picture a mix between James Bond, Tyler Durden, and the Dos Equis guy
When it is raining, it is because @Not the NSA is thinking of something sad.

Not the NSA's cereal never gets soggy. It sits there, staying crispy, just for him.

The acronym NSA play means “no strings attached.” As in, I'm not looking for a girlfriend, boyfriend, or serious commitment. I just want to have fun. People who are looking for no-strings-attached dates want a casual sexual encounter without making any promises about the future.
