A Smutbadger is a person who lurks around public places for anything that could possibly be dirty, including skimpy outfits, attractive people, or even dirty phrases.
A man who frequents restaurant bars with a t-shirt that has the word "slutbanger" on it. This man can and will bang any slut that makes eye contact with him. His hands, while delicate enough to roll a perfect pie at his mon-fri job at pizza hut, can be deadly enough to "wipe the floor with you." His 6'2 220 lb frame is a force to be reckoned with.
Jim: don't bring your girl to the bar tonight bob, slutbanger is going to be there.
bob: who?
jim: some dude that willchoke-slam you through a table, then have sex with your girl on top of your lifeless body.
