I have perused some dota 2 trading forums. Certain items/terms are appearing often, but I'm just not sure what the jargon means.
The terms - Hook - TB - Old Key
They are what I am unsure about.
I've seen some people jokingly refer to the "hook" as Kunkka's pirate hook, though I'm fairly certain that's not really what it is. I doubt TB stands for tuberculosis. And, what is an "old key" compared to any other key?
