[a skill] is my middle name

[alpacinou]

Is it correct to say "[a skill] is my middle name" when you want to say you're good at something?

Are these correct and natural?

1. -Can you make a good salad? +Are you kidding?! Making salad is my middle name.

2. Can you make this problem go away? -Yes, making problems vanish is my middle name.

3. Can Ana throw a good party? -Yup! Throwing wild bashes is her middle name.

Yes, but those aren't natural. Instead, try:

1. "Salad maker" is my middle name.
2. "Problem-solver" is my middle name.
3. "Party hostess" is her middle name.

As "party girl" has sexual connotations, it wouldn't work for the third one.

This construction was parodied in one of the Austin Powers movies, where it was used in a literal sense for comedic effect. Danger is my middle name.

You can use pretty much any situatuion you wish to suggest you're proficient at or to suggest something difficult is routine for you. While common, it's almost always used facetiously. While I've heard it used many a time, I don't know that I've ever heard it meant seriously. It's usually an attempt at humor, or perhaps as bad B-movie dialogue.
