Sperging out 

When someone goes on a long, in-depth, overly elaborate explanation long after everyone already gets the point, but will not fucking end. You get the point, but the person continues to explain their point, and often times stutters and stammers whilst doing so.

The explanation often times has to be cut off, or tails off if they realize that no one is listening to them any longer.

The definition above this is an example of "sperging out."

Sperging out 

Behaving like someone with Asperger's syndrome, or needing to go home and shut yourself off from all human contact for a while.

This party is way too crowded. I feel like going home and sperging out for a while.
