To stuff a Dreadnought (preferably one of the old metal ones) into a sock & then smash it into the cheating/cheezey army list using player's face.
This usually results in pain for the offender. This is a good thing.
However, never Dreadsock Chuck Norris, don't even think about it unless you want to have your testicles crushed. It hurts, believe me.

Gaming term from the Warhammer 40,000 hobby.
A Dreadsock is a standard sock with a (metal) 40K Dreadnought inside. The Dreadsock is then used to 'beat the stupid/cheeze/beard/shit' out of people.
In general useage, "Dreadsock" is usually suggested to emphasise how stupid a situation is.
Note: it is not advisable to actually hit someone with a real Dreadsock - it can cause serious injury, and get you in a lot of trouble!

"Take one Dreadsock, and apply as many times as needed to make him stop."
