More cowbell

[Rihanna]

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 Dont 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 Farrells cowbell playing, and demanded more cowbell on the track.

[Donald Trump]

More cowbell is the reason that Blue Oyster Cults mega-hit Dont 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.)

1. an element of music synonymous with more rocking.
2. an increase in rockage.

[Tanya Shivari]

1. The only way a song can reach perfection
2. Everything needs more cowbell, NO EXCEPTIONS.
3. Christopher Walkens greatest line from SNL, it is UN-FUCKING-BELIEVABLY funny

[Little_Girl]

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.

[Jessica]

Generally speaking, when it becomes apparent that either a person or group of people need to step up their game.

[Justin Bieber]

No definition. This dictionary just needed more cowbell.

[Tina]

An adaptation on the popular phrase used by a facebook user group whose purpose is the encouragement of facebook content and humor revolving around the satirical cowbell metaphor made popular in a Saturday Night Live skit. The SNL classic mocks Blue Oyster Cult members (played by Will Farrell, Chris Kattan, Horatio Sands and Jimmy Fallon) in the recording studio where they are laying down Dont Fear The Reaper with record producer, Bruce Dickenson (played by guest host, Christopher Walken) who advises the fellas that they are going to want that cowbell in their sound and the track could use a little more cowbell to an already cowbell prevalent song.
A (subliminal) tool used to politely suggest to your long lost pal to add some content to their facebook profile.
The classic request for more facebook content.
A facebook classic.

[Britney]

The thing that puts babies into gold plated diapers.
The only way to become the cock of the walk, baby
