A combination of "to shock" and "to rock".
My book is going to shockrock the publishing world into a frenzy.
The rollercoaster was a total shockrock!
also refers to bands with gory, sexual, or down right nasty lyrics like the band Cannibal Corpse who sing songs like "I Cum Blood." You can already tell how graphic the lyrics in that song.
Other bands in the "Shock Rock" genre are Alice Cooper, W.A.S.P., The Mentors, The Dwarves and GG Allin.
"Dude that W.A.S.P. concert was awsome i love how Blackie Lawless spits blood, damn i love shock rock"
