Open-bomb
When someone opens a Snapchat sent by you but doesn't reply. Is particularly annoying when making plans or wanting to have a conversation.
Dude 1: I haven't spoken to this guy for a while. *sends snap*
Dude 2: *opens, but doesn't reply*
Dude 1: Dammit, I didn't know this fucker was an open-bomber!
Dude 2: *opens, but doesn't reply*
Dude 1: Dammit, I didn't know this fucker was an open-bomber!
