I think it is a metaphor. Metaphor's are like similes but don use "like" or "as".
For example: I am a pig at dinner.
That is a metaphor because I'm saying that I'm a pig at dinner, but I don't literally mean it.
For a simile:
I am like a pig at dinner.
I say like because I'm comparing myself with a pig. And I used like. So it makes it a simile.
I hope that helps! :)
So the answer is metaphor.
Connotation is a feeling that happens inside you when you see a word.
