Sigma Grindset 

When you finish masturbating while your parents are knocking at your door. When you invest in dogecoin. When you only talk about Elon Musk. When you edge yourself for 6 hours. When you go to bed at 3am and wake up at 3:01 to start your morning edging session followed by a 35 mile run at 4:30 pace. When you cut off all of your family and friends to invest in the rare fish oil market. When you drive your car into your local church because the pastor didn't give you that sunday services offering.

Did you see Johnny killed his family? He's on the sigma grindset!!
