means To bump, push, or knock against someone or something, usually while moving through a crowd.

from Jostle grew out of Middle English 'justen' — to joust, as in knights charging each other with lances. Add the frequentative suffix '-le' (the same trick that turns 'nudge' into 'nuzzle') and jousting shrinks from battlefield collision to the everyday bump of elbows in a crowd. So every time you jostle someone at a sale rack, you're technically jousting them, just without the horse.
