"lambo doors" ouch, my inner car hurts.

A very kind lady who devoted her life to educating the mentally handicapped coined the term "Tard Story" they don't even originate from 4chan. Its the internet, learn to have a laugh.

That's sweat. Comes from a funny video about his significant other asking him why the cookies are cleared on their laptop

You don't have to understand other people's sense of humor, no one is asking you to.

You are not being attacked, Everyone has different opinions on what is acceptable to joke about. I have joked about all things you have listed as well as religion abortion and dead babies. I personally like dark humor. Here on the internet, it is best to not take things too seriously and accept difference of opinions. You may debate all you want, but keep in mind you will change no ones mind.
