alligator
n.— «Summertime on Interstate 81 can be dangerous. It’s alligator season.…Those “gators” aren’t wayward reptiles searching for a cool mudhole, but trucker lingo for tires or retreads that have flown off trucks and cars and are strewn about the roads.» —“‘Gators’ Lurk On Interstate 81 They Look Like Huge Reptiles And Can ‘Bite’ Just As Hard” by Zeke Barlow Roanoke Times & World News (Va.) July 3, 1999. (source: Double-Tongued Dictionary)
