the time of day when everyone spams your snapchat feed with a black screen and a clock just to let everyone know that they're crushing on someone when it's obviously not gonna last
The time of the day where you make a wish and post it on a black picture with the time on snapchat. People usually add a caption, which hints towards their wish. The most used topic for 11:11 is your crush or girlfriend/boyfriend. If it's your crush, then good luck trying to get them, as it's one of the ways to not get a girlfriend/boyfriend.
Guy 1: Hey look! It's 11:11! I wish for the girl that I like!
Guy 2: Don't you also mean the one that you aren't going to get, if you keep this up?
