grackle

For those living in the British Isles, grackles are groups of tourists. Grackles typically pour out of busses onto streets, blocking regular foot traffic and creating a general nuisance. Ironically, the more a city complains about grackles, the more it probably needs grackle tourism money to stay out of bankruptcy. Typically, one can find grackles flocking outside of major historical landmarks and international fast food chains. Grackles come from all continents.
