To sleep on someone means you don’t believe they’ll actually achieve something they said they would or will do. It’s basically someone calling you bluff on something you say you’ll do, but instead of them verbally calling you bluff, they’re thinking it. Its thinking that someone will stay stagnant in a journey, process, career, etc. It’s a lack of respect towards that person either because they haven’t done it before or because you don’t believe in them. Basically, if someone is sleeping on you, you’re not a threat nor respected by that person and this is a time to prove that person wrong.
The other day, I told someone I wanted to be an oscar nominated actress. She laughed in my face and said “yeah alright sure thatll happen”. I laughed and told her “don’t sleep on me”.

You have been awake for 18 hours and are now viewing this useless definition of sleep. You are very tired and your brain is not functioning at its normal capacity. The bags under your eyes are starting to weigh you down. It's 1:30am and you have to get up at 6:30am for work. Another coffee wont help you now...
Turn off your computer and get some sleep you net junky!!
