Usually clothes that are vintage ie. more than 20 years old, no longer available by a designer brand, out of stock, therefore, deadstock. An example of vintage deadstock can be gold label Levi’s for example. These key words can attract buyers of vintage designer labels and can be used as a description when selling vintage clothes online. Used with a hashtag #vintage deadstock.
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!
"This guy at my local club insists on using illegal rules combos and claiming it's legal! We've tried time and again to make him learn the proper rules! How do I get through to him?"
"Take one Dreadsock, and apply as many times as needed to make him stop."
