smelling like a rose

To be in trouble and/or tough situations, with everything and everyone seeming to be against you, yet you come out on top, no worse for wear.

I came out of it, smelling like a rose.

POSSLQ (pronounced "possle cue")

Person of the opposite sex sharing living quarters. This used to be a Census Bureau term and may still be one.

My POSSLQ (pronounced "possle cue") and I have an agreement on who takes out the trash.
