There are so many to choose from!!
I work where my kitchen is mostly Spanish speakers and I have really come to learn the saying "ay dios myo " cause when things mess us or something doesn't come out right this is what they say and it brings such a smile to my face cause I thought that this saying was only said in movies. But it's real life.
Secondly, I am an AVID otaku! So the simple word "noni" is everything. It means "what" and not just the simple way of "what" but what the hell, are you serious, no way. The dialect and tone must be used differently to understand which is being used. So I use the phrase in my day to day!
There are more phrases I love a lot but these two are by absolute favorites and my butt is getting numb from sitting on the toilet too long lol👌🏾💩😘
Fun homework!
