look up any word, like jamflex:
 
1.
a vagina belonging to a very nasty looking woman.
(it most likely smells like an old boot)
-I can't believe you hooked up with that chick...
-yeah i regret it, she smelt like an old boot.

-(see's fat girl jogging)
-check out that sweaty old boot!

2.
An affectionate form of address, usually said by a man to another man, indicating your level of comfort with that person is equal to that of an old, well broken-in boot (as opposed to a cramped, new shoe.)
Thanks for letting me borrow your car, and loaning me gas money.

No worries, old boot, we go way back!
