My family has some really weird vocab, stuff other Portuguese speakers don’t use:

• picopato - pot rest (actual name: descanso de panela)
• cupesca - wooden spoon (actual name: colher de pau)
• fuéun - a measurement unit, between a level and a full tablespoon
• levar aqui - to bring, literally “to send here”. (actual verb: trazer)
• curica - the household cats, when you either don’t know which one did something or you’re talking about both at the same time
• aguete - when you ask what’s for lunch, my folks typically answer “aguete!” to convey “shoo, let me cook”.
