A scientist, usually of the younger generation, who feels cool wearing his/her lab glasses (or laser protection goggles, VR headset, whatever scientific headgear he/she wears).
Reference to the 80s movie Robocop
Dave and Simon sit in the laser lab. Dave has nothing to do and puts on Simon's laser protection goggles. Gareth walks in and gets a suspicious look from Dave. Gareth says sarcastically "Oh no, it's robodork!" (All done in friendly irony, of course. Scientists enjoy irony.)
