/vt/ - Virtual Youtubers

risu made a very racist tweet about "geese chamber" which is clearly a funny way to say "gas chamber", such as the devices used in WW2 by nazi germany to gas jews to death in concentration camps.
The video she attached to her post is an angry man yelling at a bunch of geese to get in the chamber. As soon as he starts shouting they go inside to meet their certain doom.
Such a tweet only 3 days after May 9th, the official date of WW2 ending and nazi germany surrendering is quite a weird "coincidence". So I ask you: What did she mean by this?
