Non-racial definition: a group of people who travel from place to place, generally causing a ruckus and fleeing the scene. Kids are often worse than the adults, very charismatic but absolute devils. Will rob you blind without hesitation. Adults get shit-faced, children will too, but off of other people's booze. Common traits are throwing pennies, paying in large bills (yes, even the kids) but never by card, and wearing flashy expensive clothes to get attention. Gypsies are unnervingly charming. Many gypsies look identical and have a lot of kids, all of which try too hard to look innocent. If in public, all will abuse staff by verbal, physical assault, and trashing the place they are visiting. (Eg: intentionally jamming coins in the bill slots in vending machines/atms, clogging toilets and sinks, leaving food everywhere, breaking bottles/glasses, spilling drinks, etc.)
If you see this group, expect trouble.
