Frosty Booster

The term is new to commercial rocket engineering, most frequently involving the testing of rocket boosters with cryogenic liquids, like liquid nitrogen. The vehicle becomes covered in ice condensing on the cold surfaces. NASA rarely showed this as their vehicles tend to have insulation that prevents the boosters from becoming frosty. This is more common with SpaceX and other commercial launch testing.

Oh look, a Frosty Booster is on the test pad getting ready for a launch.
