A gielliane is a person who spells her name with a g to avoid extreme basicness. Gielliane is used to describe one who is extremely sassy and black although not resembling one on the outside. She is too little to be referred to as a nigga so instead is a niglet. She is classy sassy bossy and phat all in one black girl. #phatphreshandphlytodeath
