unopenzone

When you send a message and the other person reads the notification but does not open the app or making any physical effort to reply. It means that even though the person who received the message may be active, they did not open the other person's message hence the person who sent the message will not be seenzoned. This is usually done to read the message and then later make up the excuse that you did not see it nor did you seenzone the other person

Person 1: *Texts Person 2*

Person 2: *Gets and reads notification*

Person 1: "Man I got unopenzoned"

Person 3: "Feels bad. At least you didn't get seenzoned though"

The only form of disrespect that exceeds being left on read. Usually anywhere from forty minutes to an hour people know you've reached out.
