Christian cocksocked Skov five times on Sunday while Skov was hanging out with his girlfriend. What a cockblock for Skov-- he was doubled over in pain for the rest of the night and his girlfriend left early.
A "CockSock" is jargon for a condom that you would place on a male's penis.
The name draws from the comparison of applying your feet with a sock to putting a condom on the cock with both being practical as protection as well as both being rippable due to lack of care.
