Dobblering

Coined by the great Jay Dee, after Lloyd Dobbler, because Say Anything taught an entire generation of nice guy autists they're just one grand, romantic gesture away from winning the girl. The behavior of spamming a girl on social media with a surplus of likes or reacts going back a creepy duration of time (years) but rarely if ever actually speaking to her personally.

That dude is a sad case of dobblering, he liked every selfie I've ever posted within 20 minutes but has never even spoken to me.
