Recignore
Recognizing but ignoring, pretending to never have met that someone you've seen in the library all year but never talked to, your only meaningful interaction that one time when you awkwardly made out with his or her marginally more attractive best friend at a terrible frat party.
Jessica recignored that one dude for three years before he came up to her and confessed his undying love for her, to which she responded with "Lol no".
