It usually starts here with some scuffle with an interloper and then one or the other gets their posts deleted or tossed onto the pokey.
If it’s off Q-thread, it’s usually bags fighting a circle of the usual protagonists; once it gets rolling, the mods step in. I think this time it was off-Q. I missed it :(
Hopefully someone tossed Bags his mitt and ball on the way in the cooler like McQueen in the Great Escape.
