Emasculated (male) Prius owner. Sensitive and sensible male who looks like a phallus yet most likely does not use his own. A man who has checked his manhood at the Toyota dealership.
It is the band Primus' slogan, meaning that you would say it if you really like primus. they got sick of the slogan after awhile but some people still say it because it's a great slogan, so if you see someone post a comment on a youtube video of primus and they say primus sucks give them an E-high five.
