Procrastination at its best

So, I'm trying to avoid studying. Success thus far! :D
Anyways...I thought I'd share some words I'm fond of:

1. Gee: Used sarcastically. Best thing ever. People should use it more often like "Gee, thanks for the advice." Trend begin.

2. Ridic: My new favorite word. Use in instances where something is crazy or ridiculous--like: "That shit is ridic" It's awesome, trust me.

3. Humph. Great sound effect that should be used in real life and spelled out on the internet.

4. Nice. Appropriate one word response to things you find awesome. Great substitute for awesome or great or sweet!

Okay. Those are all I've got. But I do have a question: Why do some people use "haha" instead of "lol"? As someone who uses "haha" in a sarcastic manner online it can throw me off to read "haha" in a non-sarcastic manner. I think some of my friends are not actually laughing at my jokes. It hurts my feelings. (Just kidding) I've been trying to switch 'em up recently but I'm still struggling to incorporate "haha" into my non-sarcastic vocabulary. We'll see how that goes.

Peace.
