These are a few things that I come across often here and on YouTube (Since that is the only other website I visit that contributes a lot to the internet) and I'm not sure if I should make entries for them or not:
Worth the Weight – A phrase often associate with Gabe Newell / Valve that references the long amount of time it takes for valve to make new games. I'm not sure if I should make an entry for this as it's only kind of common.
Half-Life 3 Confirmed – Another phrase referencing the fact that it has been a long time and will still be a while before the game Half-Life 3 is released. A small spike in usage appeared after/during E3 with this; (PS)4 – (XBox)1 = (Half-Life)3. I'm not sure if I should make an entry for this because it's mostly only used by Valve fans.
Bill Nye – A fairly popular scientist known mostly for his show "Bill Nye the Science Guy." Not sure if I should make an entry for him because he's popular, but not internet popular
"I think it's trying to communicate" – A common YouTube comment often in reply to a comment with such bad grammar and spelling that it is not readable. Not sure if I should make an entry for this because it's mostly exclusive to YouTube.
Twiface – An exploitable image of the character Twilight Sparkle from My Little Pony making an odd face and looking at the viewer. Often associated with the phrase "You're in the wrong neighborhood motherfucker." Not sure if I should make an entry for this because it's a brony specific meme.
