Idiom
To include an idiom in an example sentence, simply incorporate the idiom naturally into the sentence to convey a figurative meaning. For example, "She had a chip on her shoulder" is an idiom meaning she was easily offended or held a grudge.
An idiom usually is a sentence, or part of one. It certainly can be used as part of a sentence. The way to tell if it's an idiom is if it makes sense the way it's literally written.
No it is not, it's just an idiom.
