"Panhandling" is so last century. Around here (SF Bay area) it's what a lot of kids (even some affluent ones) do after school in lieu of a job. It's called "spanging" now, a portmanteau of "spare change."
Portmanteau: also called a blend in linguistics, is a combination of taking parts (but not all) of two (or more) words or their sounds (morphemes) and their meanings into a single new word.
