Bonn derives from the word 'bint'. It became 'Bonn' when some people pronounced the 'i' in
bint like an 'o'. it has since then evolved into
BONN.
(it is also the last name of
Terri Bonn)
Some random : 'Look at this! I can
jump off this and live!'
*he falls,
breaking his legs*
Me : 'Oh, you really are a Bonn'
