can you guess this song

He is a hustler, he's no good at all
He is a loser, he's a bum, bum, bum, bum
He lies, he bluffs, he's unreliable
He is a sucker with a gun, gun, gun, gun
I know you told me I should stay away
I know you said he's just a dog astray
He is a bad boy with a tainted heart
And even I know this ain't smart
