A girl that is cute, crazy at times, somehow angelic due to her randomness and her charisma. This person is hard to be known at first, once she opens up on you, you'll be surprised that how funny and attractive this person can be. Prefered to be called Nini (read : sloth) and this person is adorable to the max.
Cute charismatic adorable, innocent, random in cuteness

Slang in Mexico for a young person that 'ni estudia, ni trabaja' ... in other words, someone that doesn't study, and doesn't work. Just sorta bums around all day, and lives off their parents' money.
Ese nini no hace nada, solo pasa todo su dia en la playa.

That nini doesn't do anything, he just spends all day at the beach.
