List of League Terms Everyone Should Know.

I don't know how but we seem to have gotten some people who managed to get to level 30 without learning these so here goes.

OOM: Out Of Mana - they have no more mana in there bar, you should not do anything that would normally require them to participate with skills.

BRB: Be Right Back - they are leaving lane and you should watch yourself.

Respect: - Something to be feared (or caution) and understood. Example: Respect the Leo Dive - they are telling you that Leo can go all in dive on you and really ruin your day. So play with fear and understanding of that fact.

MIA: Missing In Action - someone is missing and may be coming to eat your face. Assume you are about to be jumped by someone at any moment and should be checking your map every few seconds. Be paranoid.

Dive: -Charging head long into the enemy regardless of location (under tower).

All In: -Holding nothing back for later using every skill and item at your disposal.

Ult: - A champions R skill (often the most powerful)

CDR: Cool-Down Reduction: It's Cool-Down Reduction, if you don't know what that is go look at the game information section.

Gank: -Someone coming to a lane or area that is not part of there lane in order to attack the enemy.

I'm sure I'm forgetting some but these are the ones I commonly get asked what I'm talking about.
