One way to hold this word: pushing at close quarters. Two people are near enough to grab each other, so nothing is aimed and nothing is — arms get in the way, feet slide on the ground, and it is over in seconds. Keep the pushing and drop the other person, and you get feet that along the floor. Keep the pushing and make the other side daily life, and you get someone getting by on very little.
From the word’s history
The supplied source says the word is possibly of North Germanic origin, comparing Swedish skuff, a push, and skuffa, to push, from a root meaning to shove. The source hedges this itself, so treat it as a likely route rather than a settled fact — but the idea of a shove does sit under every sense in this group.
手上的來源說這個字可能來自北歐語系，並拿瑞典文 skuff（一推）、skuffa（推）來對照，底下是一個表示「推」的古老字根。來源自己用了「可能」，所以這是一條很像的線，不是定論。不過「推」這個畫面，確實在這一組每一個意思底下都看得到。
