This word is I'm pretty sure US slang and I'm pretty sure a monosyllable. It means something like 'wash' as in 'A lack of progress or regress; no change' (Wiktionary): non-starter, no-show, damp squib. I think it might typically go with the indefinite article, like 'wash' in this sense. What is it?

I don't know...anyone else?

However, I wanted to say welcome back. Pull up a chair and stay awhile!

bust?
