A 'walk of shame' is when someone has to walk past a crowd of people feeling really embarrassed for whatever they have done. For example on a drunken night out, let's say one threw up and got kicked out of the nightclub. This would be shameful for the person.
It's singular when it's used with a singular subject ("I walk," "you walk") and plural when used with a plural subject ("we walk," "you [plural] walk," "they walk"). What is it not is a third-person singular verb: you can't say "he walk."(Actually you can say say "he walk," but hardly anybody understands the present subjunctive any more, so let's just say you can't say that, at least not in ordinary idiomatic and grammatical English discourse.)
shameful conduct;scronful reproach or contempt;cause shame or disgrace.
The likely word is "embarrass" (to cause shame or chagrin). Example sentences: "Don't embarrass me!" the girl yelled at her overly protective mother. The bully said mean things in an attempt to embarrass an unpopular student. To embarrass someone is to point out a real or perceived flaw in another person, or to say something in front of other people that is intended to shame a person.
If a person feels shame, then they are "ashamed". If an action deserves shame, it is a "shameful" action.
I think you mean 'disgrace' Which used as a noun means - the condition of shame, loss of honor, respect or reputation. and when used as a verb means - to bring shame or dishonor on someone or to treat with disfavor.
