Rickrolling (wikipaedia link) is where you post a link, pretending it’s something relevant, but it’s actually a link to Rick Astley’s song “Never Gonna Give You Up”. My suggestion was that Star Trek fans, if playing the same trick, should instead post Leonard Nimoy’s Bilbo Baggins Song.

[Edit] And without “Rick” it’s not Rickrolling - and with Spock/Nimoy, I was suggesting “Spockrolling” or “Nimrolling” as possible alternatives that would work in the same way.
