/uma'rɛl/ (oo-mah-rell), n; pl. Umarells. People in a community who offer all sorts of comments to those who are trying to get some work done, but who are not doing any work themselves.
Umarell is a word that entered Italian slang in Bologna and is spreading to nearby towns,
occasionally even across Italy. It comes from the Bolognese for "cute/odd
little man".
"Umarells" are those people, usually retired men, who spend time watching
construction works, often holding their hands behind their back, occasionally commenting on what is going on, sometimes trying to tell the workers what to do.
