A phrase that came into popular culture through a Saturday Night Live skit with Will Farrell.
In the skit, Farrell portrayed a member of the 80s rock band Blue Oyster Cult as they recorded their classic hit "Don't Fear the Reaper" in the studio.
Farrell played the cowbell quite forcefully on that track, much to the dismay of the rest of the band.
Yet surprisingly, the studio producer loved Farrell's cowbell playing, and demanded "more cowbell" on the track.
That was brilliant, man, the track needs more cowbell!

More cowbell is the reason that Blue Oyster Cult's mega-hit "Don't Fear the Reaper" reached such heights. While recording the song, the cowbell track was barely audible. It was the sharp ear of the producer who stepped in and demanded "more cowbell."(After all, he did know how to make hit records.)
Gentelmen, if "Don't Fear the Reaper" is going to be a smash, we need to hear more cowbell.

From the satirical Saturday Night Live sketch featuring Will Ferrell, now used as a way to tell someone when something they did was good, but just not quite right. The phrase "more cowbell" works to express this mild dissatisfaction in a variety of settings.
At a steakhouse "how was your meal?" It was ok, but could have used just a little more cowbell.

"Eh, that ,movie wasn't bad. But really could have used some more cowbell."

"That was a good blowjob honey, but really could have used some more cowbell"
