"caboobers" are great! Though I'll have to be careful expressing a liking for them, I think. Especially in the case of rollicking great big caboobers.

Isn't "doohickie" a verb, meaning "give a love-bite to"?

..and I've been told that "widget" is the official name for the thingumajig that lives in a beer can (especially Guinness) and injects nitrogen when you open the can, thus providing a "draught beer" effect. Or did I imagine it?

Sorry, my standards are very exacting, I know.
