A sexual innuendo
. Commonly used whenever someone makes a hesitation sound such as "uh" or "err", but it can also be used whenever someone is moaning, groaning, complaining, or simply trying to come up with an excuse to hide the truth
Can be used given the right time regardless that you were originally in the conversation. Be warned though, results may vary.
