a way of making a 4:20 smoke session that you weren't properly prepared for by not checking a clock again after seeing it says 4:20. According to Shrodinger, it is both still 4:20 and not 4:20 so long as you don’t see a clock, so take your time and smoke when ready!
Dude, we’re gonna have to do a Shrodinger’s 420 because I still have to roll a joint!
