Your favorite sayings?

[RICHARD]

I don´t know (actually in english)
si no le gusta bye... (if he/she/they don´t like it... bye)
esta bien... (as in nodding not so convinced about somehting)
hijo de tu madre!!... (not a bad word, it mean son of your mother, which is actually true isn´t it )

My dad's favorite was 'Hijo de la guayaba'!

translated? Son of a guayaba-which is a tree fruit.

And "son of a boliche', said with a thick Mex accent!
"Son of bowling!"

I don't like the saying,
"It is what it is"....ugh!
