a 'Hollowayism' - derived from thought process occuring when said Holloway-scientist-type brain becomes blurry thru exposure to alcohol and sleep deprivation. Also used to describe face of said scientist once he'd 'snockered' himself.
Holloway would have made it home in time for tea but being 'snockered', had fallen asleep with face on desk. As usual this led to face having imprint of calculator for rest of evening. Such unbecoming appearance was due to having 'snockered himself'
