Kakuna
A fat, hard aunt that your mom’s sister is known for in some f*cking Hyderabadi-Chennai households. It's like a term for your aunt, but spelled like a f*cking cock.
My Kakuna was my mom's sister and she was as hard as a brick.
I called my aunt Kakuna and she got mad and said I was f*cking annoying.
My Kakuna was the hardest aunt I ever met and she just sat there like a f*cking brick.
