Used to say that you do not care or that something is irrelevant to you. (It refers to the idea of something being slippery like grease, so the situation just slides off you.)
An expression used to show indifference or that something was just okay. It describes something mediocre that is neither good nor bad, similar to saying meh or neither here nor there.
I went out with my ex yesterday but the truth is it was just ni fu ni fa.
Refers to a person who is completely indifferent or unbothered by what is happening around them, regardless of how serious the situation is. (The term refers to not tuning in to surroundings, like an antenna that refuses to receive a signal).
That guy is so antiparabolico! The roof could be caving in on him and he would not do a thing.
An onomatopoeic sound made by sucking air through the lips to express annoyance, disgust, or indifference (it is the local equivalent of sucking one's teeth).
