Begging is the practice whereby a person obtains money, food, shelter or other things from people they encounter by request. It is also referred to as sponging, spanging (short for "spare-changing") or (in American English) panhandling.In larger cities, it is common to see beggars asking for money, food, or other items. Typically, beggars often beg for spare change equipped with coffee cups, mugs, small boxes, hats, or other items into which monies can be placed and sometimes display signs with messages such as "Help me. I'm homeless."
