I've removed the bounty. From your bounty notice:
The bounty will go to the best implementation of a right click jQuery plugin.
That's not valid for two reasons. First, it's not constructive, and you are the one that's arbitrating the decision of what the "best" is, in that only you can award that bounty.
Second, it's a "gimme teh codez" request. What is the actual problem you're facing? From your statement, there isn't one, it just reads that you are either a) lazy or b) trying to foster a code competition with rules set by you, neither of which is appropriate for Stack Overflow.
To answer your question, no, you aren't allowed to spend your rep any way you see it. We're actually pretty liberal with allowing you to spend your rep how you want (downvotes, bounties) but it still has to work within the general guidelines of the site.
This all begs the question of why you did it in the first place?
What is it you're really trying to accomplish with the bounty, and what is wrong with the most upvoted, accepted answer that doesn't suit your needs? If you elaborate on that in the bounty reason, then it would have a much greater chance of attracting the right kind of attention to the question.
