People who have to use a nickname for everything, especially airplanes. Is it really that hard to spell out Bonanza or TriPacer? "I fly a Bo". "My friend has a Tripe" "How many years did Beech build the Mouse?" "Did you see Bill's new 'Hawk" "My friend has a really nice Twink." (this one can have a whole different meaning) And then there are those who have to give everything they own a name.
