Even dumb people have found a way to abbreviate. IDN stands for "I don't no." An educated person says "I don't know," which can be abbreviated to "IDK." If you see someone that types "IDN" on a regular basis, you know that their IQ isn't very high.

NOTE: If said person is dumb enough to use IDN, I doubt they'd take the time to use capitals, making it "idn."

You may also see "IN", or "in," which can translate into the opposite: "I know," or to an educated abbreviator, "ik. "
First dumb person: hey britney do u like jake
Second dumb person: idn i here hes pretty dum
First dumb person: but hes so hott
Second dumb person: ya in lol

Translation:
First smart person: Hey, Britney, do you like Jake?
Second smart person: I don't know, I hear he's pretty dumb.
First smart person: But he's so attractive.

Second smart person: Yeah, I know.

When the “crush” has no intentions of taking things further, but they like the attention. So they flirt here or there, send dm/texts just to keep the person interested, knowing damn well they’re staying single.
Danielle was so flirty the other night, he messaged me 3 times just to say hello, I think he’s coming around.

No Susan he’s breadcrumbing you just so you’ll keep nibbling at his heels.
