When one is in the presence of rock and roll style music one tends to display actions which are of quite uncanny nature as compared to daily actions. These actions combined with an essence of hardcore and "rocking out" has been often coined in popular culture as being 'rockcore'
"Hey Brad, how did you like the concert last night?"

"Man, Tommy, it was totally awesome, everyone was going wild, the people in the mosh pit were totally rockcore!"
