The heavy Spanish accent from Mexicans/Latino kids trying to say "Trick or Treat" when they go to the rich white neighborhoods that always give the best candy on Halloween.
"Hola tricotri!"
"Oh look we have Spider-Man! And Cinderella! And you son, who are you supposed to be?
"Yes. TRICOTRI!!!"
"Oh not much of a talker are ya? OK here's your candy kids! Happy Halloween!"
