Nicknames for things other than people you know.
Do you ever call things by a nickname or shortened version? I don't do this often anymore, but when I was a teenager I'd frequently call things by silly names.
The 2004 Battlestar Galactica series was known as 'Canadians in Space' when I'd bring it up.
Futurama got shortened to something pronounced few-chee. Never spelled out this abbreviation, but it'd probably be Futchy.
I'm sure I did this with other things, but those are the two instances that spring to mind.
