The term 'bobby-laugh' denotes a laugh of excessive measure and volume, deemed by the audience, given the stimulus that prompted the laugh.

A 'Bobby-laugh' nearly always follows a comment that is either mediocre in its comical value, or not funny at all. What seperates the laugh from a standard laugh is therefore defined post-joke; upon review of whether the magnitude of the laugh coincides with the comical level of the 'joke'.
