On one day a year, nobody texts their crush (unless there’s an emergency).
This means that if you don’t get a text from your crush, then perhaps she/he might like you back. In any case it relieves some stress and you have an excuse not to text her/him.
I didn’t text my crush on National “don’t text your crush day”.
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
