Can be used to describe someone you'd normaly call a cunt-prick-or twat, infront of more sensative people, children not used to street banter and old people that mite not understand more modern cussing, blaggard and bounder are ok,but cunt's still got the edge in my opinion, knob rocket can be an ice breaker, once the subject is used to your silver tounged urban banter, you can ease them into more progresive cussing.
Dont listen to that knob rocket! He's an arrid banquet (one up from a drylunch.)
