No, Kevin. To bugger is the verb. Also, a noun. You daft bugger. It's a right bugger is that. But a person with a predilection for the particular activity in question can't be just a bugger. A person who's inclined to wander is a wanderer, not a wander. A person who's inclined to bugger is a buggerer, not a bugger, at least in intent if not in practice. Of course, a buggerer can also be a bit of a silly bugger as well. Hope this helps.
