Is it normal that i dislike my step dad for no good reason?

My mom has remarried twice and this will probably be her third time. Her first husband, my biological father, would hit her; he broke her nose. Then, she got together with a guy who was nice only when he was high. Now, she's with this nice guy that she says she's happy with.
Regarding my feelings toward all of them:
Biological father: Prick; haven't seen him in years and don't intend to for as long as I live.
Second father: Used to like him when I was little, but then I realized he was an asshole for various reasons.
New boyfriend: Pushover. I should like him since he's super nice, but I REALLY don't. I don't like people who are too nice. I think he is very annoying. He's always making crappy jokes and teasing me about stupid shit(e.g. I talk about a guy friend at the dinner table and he's all "Oh, do you like him? Is he gonna be your new boyfriend? When are you bringing him over?" when all I said was "he helped me with math today, I thought it was nice").
Every. little. thing. he does, annoys the hell out of me. For example, we get up at around the same time(him to go to work, me to go to school) I wake up and I get up from bed to do my daily morning routine, then I hear him coughing like a retard because he smokes too many cigarettes, and so I wait til he leaves to do what I have to do because I'm afraid I'm gonna say something 'mean' to him and my mom is gonna yell at me for it, which happens often because I don't laugh at his 'funny jokes'.
I avoid coming out of my room when I hear him in the house. I wait for him to go somewhere else so I can come out.
He also bothers my mom by saying shit like "I saw you with a guy today at the cafe. So...did you sleep with him?", and the shit isn't even true and my mom believes him and she gets really upset and he ends up saying "nah, I'm just kidding!". He even admits he likes to make her mad. WTF.
He also laughs for no fucking reason. Like, we're talking about someone who just died and then he laughs inappropriately at something my mom says, something serious and very unfunny. Plus, it's not just a little chuckle, it's a downright guffaw and he laughs for like, five minutes. I feel like slapping him every time he does it. And then when there actually IS something funny, something you SHOULD laugh at, he doesn't! He just sits there with that ugly face and looks around.
I'm gonna stop giving examples though, because I could write a fucking book full of everything he does that aggravates me.
Anyways, don't get me wrong, I'm happy my mom is happy with him, but I wish he would end up being a jerk, like the two others and that he would leave and it would just be the three of us again, my mom, my brother and I.

So there. What do you guys think? Is this happening to anyone else? Share your stories.
(P.S. sorry if this is kind of rant-ish. ><')
