League is Confusing Sometimes...

Think I'm getting pretty good with these titles...

So, after the hundred-odd comments on my last blog (thanks for the input everyone! I appreciate it all!), I've decided to take on something a bit... larger. I would like to start a blog or blog series about ALL of the skills, terms, and concepts that the community feels should be standard knowledge by level 30. I'm calling on all of you, every single person, to help me establish this compendium. I want all of you that read this to leave a comment telling a story about a time you or someone you played with/against didn't know something that caused a game-changing moment. I know a lot of them already myself, so I'll put the main ones that took me a long time to learn here, and we'll go from there.

Important Game Terms

Note: Again, most of these are common knowledge but I think they're important

Gank: When one of the opponents outside of your lane comes into your lane by surprise to try and kill you or force you out of lane

ss or SS: Mi"ss"ing. Means an enemy has left their lane and may be going for a gank. May also include the modifier "Top", "Mid", or "Bot" to tell what lane the person left from. Generally seen more on the EU servers.

MIA: Missing in Action. Same basic function as 'ss'.

Care: Used when asking a person or lane to be careful. Usually means an opponent is on the way down or may already be there. 

Conclusion

Obviously I'd like to add a lot more to this list and probably make more blogs on this topic. Any help is greatly appreciated.
