"EPIC FAIL" It used to be ok when used by online communities, but I hate preps using the phrase.
"The cake is a lie." It was an extremely clever joke and twist until it got ran into the ground.
"Because." I hate when people try to affirm their actions with this argument. If you didn't have good a reason, why would you do it?
"I lost my faith in (insert anything here)" I see this alot, and I understand where it's coming from usually, but too much.
"It's just a theory" To discredit Big Bang Theory when Creationism is a theory too.
"LEGALIZE MARIJUANA! ETC ETC" I hate this because every person who has ever tried weed will instantly start saying this, 4:20, blaze etc way too much. While I agree with it's legalization I don't walk around constantly spouting about it and how it would single handedly save the economy.
"Insert Bible Passage Number Here" I don't like it because it's mostly my Christian friends sending that to me when I talk to them like words are gonna magically cheer me up without giving me proper indication of why I should read it, or how it may help me when I'm done. Idk, I got my own problems with religion, and I don't like how when they do it they kinda make it sound like my problems are so trite that a few sentences will suddenly set me on the right path when they know I used to read the Bible and try the God thing. (Though to avoid possible flaming, I am tolerate, I just don't like being prescribed the good word when I just want to talk about something.)
