Sleeping means failing to recognize value or act on opportunities—being asleep while chances pass by. 'You're sleeping on that brand' suggests someone is missing quality they should appreciate. 'Slept on that release' means failed to purchase something now regretted. The term implies the problem is attention and awareness, not inability—you could have acted but didn't because you weren't paying attention. Sleeping is failure to recognize, while 'slept on' describes items that didn't receive deserved attention. Calling out sleeping serves as both criticism and recommendation: you should wake up and notice this. The opposite of sleeping is being alert, aware, and ready to act on opportunities. Streetwear rewards attention—trends move fast, releases happen quickly, and sleeping means missing out. Understanding what you've slept on helps calibrate future attention.
