index.html 

The name most Web servers give a home page.

Even though you may see http://www.google.com/ in Internet Explorer's address bar, it is really http://www.google.com/index.html on the server. Index.html is the only file name invisible. However, some pages have an index2.html that you can see in an address bar.

Index Finger Up 

This is when you lift your ugly ass index finger up to let people know your about to let one out, they may not know this and be startled by the disgusting smell.

John : **Lifts finger up**
Victim : ? U tellin me to wait? *Smells fart* Oh my god what’s that smell??
John : I don’t know *Turns around and giggles like a bitch*
Note : Index Finger Up is the action not the word.

index-flushing 

Continuously deleting stupid social media posts such as political comments, religious views, and generally just stupid or offensive stuff.

I spend way too much time index-flushing these stupid posts!

Index-Pinky Scratch 

The index-pinky scratch is a ball scratching technique that involves only using your index and pinky finger to scratch your ballsack. Using the hand that you pee with, you fold the middle & ring finger downwards, leaving only the index, pinky and thumb sticking out. Then you reach for the bottom of your ballsack and start dragging your index and pinky upwards, slowly and intensely. This method targets the itchy area much more effectively with needle-like precision. Note that this only works best with moderate-long nails.

I used the index-pinky scratch technique to soothe my itchy balls and have never felt better.
