What is IMYM?

Short version of the phrase: “Ima make you mine”
Used to subtly flirt, when someone is shy they use this abbreviation to shoot their shot with more confidence- it can be used easier in a conversation especially if you want to subtly validate you want that person romantically. It’s also easy enough to play off if you get rejected (like I did)*.
