This list is likely endless, so I'll put in some entries and update it periodically.
Now let's rustle some jimmies.
1. Using Everypony, Anypony, and the Like
Okay, let's get something straight here. YOU ARE NOT A PONY. You do not have hooves, a tail, twitchy ears, a snout, maybe a horn or wings, and all that other stuff. If you were a pony, you wouldn't be typing because you have GODDAMN HOOVES instead of hands. So now that we've established that you aren't a pony, let's get another matter straight. You clearly shouldn't talk like one. Tell me, do you think it's cute when you do it? You want to know what's cute? Kittens. Is the word "everypony" a kitten? I think not. It isn't cute. It isn't clever. I heard people say it's a clever pun. It is not in anyway a clever pun. It can't be defined as a pun in any way whatsoever. It is not clever. It isn't funny too. You aren't doing anything new, interesting, or not irritating. Stop.
2. Hugging, Huggles, Glomping
Man oh man, this one will sure rustle quite a large amount of jimmies. Hugs are not necessary. Tell me, do you greet everybody you meet with a hug? Is that what you do every time you see a friend? No, you don't. And if you do, who do you think you are?! A simple hello will suffice. Hugging people is weird in public, so don't bother doing it in the box. I don't care it's in text, it's stillsillystupididiotic. And when you huggle, that means you are hugging someone, and then cuddling. You do realize that no person in their right mind does that. No one. Ever. You do that with someone you love, fine, that makes sense. If you hug and cuddle someone, that actually takes the time to lie down or something. And glomping, that's a TACKLE HUG. You are TACKLING someone. I cannot stress that enough. You. Are. TACKLING. SOMEONE. I don't care it ends in a hug, you're still tackling,. I don't know about you, but I'm pretty sure I could spin that into a pretty solid accusation of assault. Here's a tip, if a sign of affection can be considered assault, you might want to question whether or not it's a good idea. Because it never is.
3. Fanboys
Oh, you like that? Yeah, that's cool. Oh, I should like it too? Well okay I guess. What's this? You're going to be a total asshat about the fact I have an opinion. Well excuse me, my behavior was clearly unacceptable, my sincerest mst sarcastic apologies. For the love of God, people need to accept the fact people like other things. It's not a crime. Tell me fanboys, is their opinion negatively effecting you? Yes it is? NO. It isn't. I don't care if it upsets you, or it's actually affecting them, who cares? Just live with it.I don't care even if they are a fanboy for something stupid, like Apple.
4. Writers Block
Damn it, I can't think of anything for this. Case and point.
More jimmies to rustle later.
