i remember watching the great kevin schwantz talking about his bikes handling to some interviewer, when asked how it felt to ride(the bike had been bucking and sliding about all over the track, but he still won) his description of 'kinda squirrely' was brilliant. complete nonsense, but at the same time a perfect description of the quick moving twitchy bike he was on. ever since, the term has been used millionsof times by people to describe twitchyness, but it always reminds me of schwantz.
