snowmobile racing term: when air is at really cold temperature it is much more dense, ie. fat air contains more oxygen for a given volume, so the fuel to air ratio can be increased yielding more power per engine cycle
have to increase my fuel to air ratio today, the air is really fat, we should get some good run times with this fat air !
