elastic-banding
n.— «My opponent, Knuckles, had a tendency to slow down when I was too far behind (it’s what’s called “elastic-banding’ in the industry), so while I did manage to win the race—over a massive track that took around three minutes to complete—I really shouldn’t have.» —“Try to keep up—we’re hands on with PSP’s Sonic Rivals” by Jon Jordan PocketGamer.co.uk (United Kingdom) Aug. 8, 2006.
