When you enjoy the way someone's bum looks from a distance, so you get to know them better. The word is often used flirtatiously or used by a children/teenagers while joking. If a odd male figure uses the word towards a adult woman, it is called a "cat-call or booty call".
DAAAAAAMMMMN, I'd love to bum-bump!!!
