I’d have to say either any version of “where are you from?” or “how did you find the SDMB?” are starting to get on my nerves…
Your anti-favs?
The SUV’s are the work of satan himself thread…
the “OMG, guess what I shaved!” threads.
I’m getting tired of “bad drivers” congregating in driving threads and trying to defend themselves. Guess what- I don’t care why you tailgate or cut me off or pass me on the right or don’t strap your kid in- you’re still an a…
whoops, we’re not in the Pit, are we?
I’ve seen the “Hey laaayyydeez, does size matter? No, really, BE HONEST” thread come up about 30 times (serious estimate) while I’ve been here.
Give it up, all you insecure males.
“what does ‘Hi Opal’ mean”?
“Thread topics you’re tired of seeing repeated?”
“Horrid Stuff Oozes From Part Of My Body (TMI?)”
- does size really matter, ladies?
- help me celebrate my ## of posts
- I’m not sure if he/she really likes me . . .
- President Bush sure is smart, eh? (oh, wait, never mind; that’s a topic I’ve never seen)
“What does your username mean?”
“Why won’t girls go out with ‘nice guys’?”
Another vote for “Why won’t girls go out with nice guys?”
This question belongs in FAQ, with the answer “Girls do go out with nice guys, they just don’t go out with whiny closet misogynists like you.”
“I’m going to Europe! Give me advice!” but only when the OP asks for general advice, rather than specific experiential information.
“Islam - The Religion of Peace” which is ironically usually titled “Islam - The Religion of War” or “Arabs and Muslims are violent by nature”
Another vote for the overanalytical why-my-life-sucks “girls don’t like me” threads.
Any ST Enterprise or Nemesis thread.
The “my co-worker’s (insert habit here) is driving me INSANE” threads. Jesus, just tell the person to knock it off and get on with your life why don’t ya?
Anything referencing post counts. What, celebrate the fact that you have way too much free time?
Thanks Euty… 
Anything referencing both Christianity and homosexuality. Enlightening the first time, makes you want to tear your hair out the 20th time. (Not that I avoid those threads, but they have been repeated a bit much.)
In GQ:
“How do I record an LP/audio tape to a CD?”
“How do I convert my home movies to DVD/VCD/SVCD?”
“Computer Question! Need help please! (with no furthur details in the thread title)”
“Is building your own computer worth the hassle/a great savings?”
In the Pit:
“I’m fcking so fcking sick of this fcking sht!!”
(Sick of what shit? If there weren’t so many bad words in the title, maybe you could throw in the subject of your rant so I know whether I want to read it or not)
Cafe Society:
"What are your favorite Simpsons Quotes?
Any thread about black people.
I avoid gay topics and/or religion topics, unless it’s LDS bashing. Although I don’t participate, the LDS threads are fun to read.
I think homosexuality topics and religion topics are overdone here at the SDMB…really.
…And another thing, you just don’t see enough UFO topics or soccer bashing topics around here… 
Underage same-sex waterfowl threads
