The loudly repeated phrase you will hear at any primus concert. it goes back to the Suck On This days, and is often misunderstood by non-fans.

Additionally, http://www.primussucks.com is the official web site for the band. Anyone who dislikes Primus would do well to curse Primus in another manner, as intoning "Primus sucks!" will likely result in grins and sounds of agreement from Primus fans. But people who dislike Les Claypool and company are obviously no fun anyway.
