look up any word, like donkey punch:
 
1.
An achievement only obtainable on youtube.

Likesabers have two forms Green and Red.

A Green Likesaber is when a youtube video is so popular, the small red bar only consists of trolls and genuine idiots.

The Red Likesaber is the opposite of a Green lightsaber, it is used to point out the overwhelming opposition to the quality of the video or it's content.

As the name suggests, it is called this because the like/dislike bar below the youtube video has achieved the proportions of a lightsaber.
Damn my shakey recording of a family guy episode got the Red Likesaber.

Amazing athiest just got given yet another Green Likesaber for his views on feminism.
