This phrase is often employed when one accidentally touches someone inappropriately, say while brushing against a coworkers bosom while squeezing past in a crowded elevator, and is used to convey that the inappropriate touch was unintentional.
One should take
care that this phrase is not mistaken for "No,
Cuomo," which roughly translates to "Please pardon my predatory and inappropriate behavior, for I am of Italian descent and
don'
t know any better."
