But, but, but...
It's getting the boot from that booter, which is like it gets kicked in the butt to get it going.
Yes, booter sounds similar to boter (our word for butter), and because the word BUT is used a LOT throughout, and because we had some fun with mach2's toasters and versions of buttered golden toasts in days long gone...

It struck me as funny, and it stuck.

Hey guys, I have to mention you can thank Mark for doing the conversion from UBB style to the style used here.
