When someone does something big that turns out to be a disappointment, like a shitty plastic rocket that goes into the air only to turn out into nothing.

When a girl is riding your cock so hard and fast that you can't get her off in time before the big purge. So you kick her in the air right as you're about to cum.

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.
