What is the definition of Pacersoft?

Ah, 'pacersoft' - a term that's as intriguing as it is slightly unsettling. Imagine it like the perfect blend of a super-efficient race car (the pacers) and a soft-as-cloth cushion (the soft). So, 'pacersoft' refers to someone who moves so quietly and smoothly that they're basically a ghostly runner on your favorite treadmill, leaving you wondering if they just walked in by magic or if they're part of a secret underground pacer cult.
