The cardboard sleeve that surrounds a to go coffee cup to keep your hand from burning when holding your coffee, usually supplied by the coffee retailer.
I stopped buying coffee at the local shop because they don't provide kilfers and the cup was too hot to hold without one.

Starbucks forgot to give Levi a kilfer with his coffee so he burned his hand, dropped his coffee in his lap, which in turn burned his junk.

If McDonalds had provided kilfers with their coffee in 1994, they would not have been sued.

Brought to public attention by Bob Woodward and Carl Bernstein in the book on the fall of Richard Nixon, All The President’s Men, ratfucker was Nixon’s term for a political operative who sows chaos among opponents; an agent provocateur. It is thought to have originated among campus political rivalries at USC, and seems to have some usage in the US military.
