Jonigram
A text message received so long after the conversation was started you don't know what the fuck the sender is talking about anymore. Often sent by a "Joner", a person who chronically and often purposefully reads messages, replies to them in their head but takes like 4,5 days to send that shit.
"Why you text me 'nothing wbu' 5 days after I text "wyd". Always sending Jonigrams.
