I gotta have more cowbell
A bunch of people on Facebook who can't stop talking about cowbells like they're the only thing that matters, even though they've already ruined the song.
My cousin texted me 'more cowbell' at 3 a. m. and I had to explain what that meant.
My friend’s profile picture is a cowbell, and he posts 'more cowbell' every time he logs on.
My brother's Facebook status was 'more cowbell' and I had to scream at him to stop.
