Rod
You all remember Rod, right? Well, let me refresh your memory. He was the super sexy, but racist bastard who was 27, but acted like he was 19. He was the loser that spent too much of his time and efforts trying to get in my pants. As much as this guy drives me MAD, I've realized one good thing about him... he never left me guessing. From the beginning, he laid it all out on the table so I knew what he was about, what he was looking for and the one thing he wanted from me. As much as he was an asshole, he never felt the need to bull shit me or pretend like he was something that he wasn't. And because of him being so upfront, I was never waiting around for him, thinking about him and he never managed to hurt me, though he did ruin even the slight possibility of anything happening at all, despite his best efforts. So, basically, guys could actually learn something good from him, as long as they don't learn to be an asshole at the same time.
