When you go normal blind and see the enemy with the same champion of yours and you starts to try hard.

You're the only one talking in team-chat

*awkward silence*

That awkward moment when someone says "I'm sorry" in game

The awkward moment when someone from enemy team types:

"Nice skins guys....*deep voice*"

in chat

That awkward moment when you call for a baron and your team gets there and its gone...

That awkward moment when your jungler dies to small golems.

That awkward moment when a Garen chases another Garen and they both start spinning

That awkward moment when your backing and get ambushed but nvr relise it till you die.

That awkward moment when your Janna, Gragas, or Alistar knocks away a kill or two
